The government and police regularly use location data pulled off of cell phone towers to put criminals at the scenes of crimes—often without a warrant. Well, an appeals court ruled today that the practice is unconstitutional, in one of the strongest judicial defenses of technology privacy rights we've seen in a while.  The United States Court of Appeals for the Eleventh Circuit ruled that the government illegally obtained and used Quartavious Davis's cell phone location data to help convict him in a string of armed robberies in Miami and unequivocally stated that cell phone location information is protected by the Fourth Amendment. "In short, we hold that cell site location information is within the subscriber’s reasonable expectation of privacy," the court ruled in an opinion written by Judge David Sentelle. "The obtaining of that data without a warrant is a Fourth Amendment violation."

In Davis's case, police used his cell phone's call history against him to put him at the scene of several armed robberies. They obtained a court order—which does not require the government to show probable cause—not a warrant, to do so. From now on, that'll be illegal. The decision applies only in the Eleventh Circuit, but sets a strong precedent for future cases.

"One’s cell phone, unlike an automobile, can accompany its owner anywhere. Thus, the exposure of the cell site location information can convert what would otherwise be a private event into a public one," he wrote. "In that sense, cell site data is more like communications data than it is like GPS information. That is, it is private in nature rather than being public data that warrants privacy protection only when its collection creates a sufficient mosaic to expose that which would otherwise be private." Finally, the government argued that, because Davis made outgoing calls, he "voluntarily" gave up his location data. Sentelle rejected that, too, citing a prior decision by a Third Circuit Court. "The Third Circuit went on to observe that 'a cell phone customer has not ‘voluntarily’ shared his location information with a cellular provider in any meaningful way.' That circuit further noted that 'it is unlikely that cell phone customers are aware that their cell phone providers collect and store historical location information,'” Sentelle wrote.

754 F.3d 1205 (2014) UNITED STATES of America, Plaintiff-Appellee, v. Quartavious DAVIS, Defendant-Appellant. No. 12-12928. United States Court of Appeals, Eleventh Circuit. June 11, 2014.

The prosecution also offered records obtained from cell phone service providers evidencing that Davis and his co-defendants had placed and received cell phone calls in close proximity to the locations of each of the charged robberies around the 1210*1210 time that the robberies were committed, except for the Mayor's Jewelry store robbery. Davis preserved his objection to the cell phone location evidence and his claim that the government's obtaining such evidence without a warrant issued upon a showing of probable cause violated his rights under the Fourth Amendment.

The evidence obtained under the order and presented against Davis in the district court consisted of so-called "cell site location information." That location information 1211*1211 includes a record of calls made by the providers' customer, in this case Davis, and reveals which cell tower carried the call to or from the customer. The cell tower in use will normally be the cell tower closest to the customer. The cell site location information will also reflect the direction of the user from the tower. It is therefore possible to extrapolate the location of the cell phone user at the time and date reflected in the call record.

HERE WAS A SIMPLE AIM at the heart of the top-secret program: Record the website browsing habits of “every visible user on the Internet.” Before long, billions of digital records about ordinary people’s online activities were being stored every day. Among them were details cataloging visits to porn, social media and news websites, search engines, chat forums, and blogs. The mass surveillance operation — code-named KARMA POLICE — was launched by British spies about seven years ago without any public debate or scrutiny. It was just one part of a giant global Internet spying apparatus built by the United Kingdom’s electronic eavesdropping agency, Government Communications Headquarters, or GCHQ. The revelations about the scope of the British agency’s surveillance are contained in documents obtained by The Intercept from National Security Agency whistleblower Edward Snowden. Previous reports based on the leaked files have exposed how GCHQ taps into Internet cables to monitor communications on a vast scale, but many details about what happens to the data after it has been vacuumed up have remained unclear.

Amid a renewed push from the U.K. government for more surveillance powers, more than two dozen documents being disclosed today by The Intercept reveal for the first time several major strands of GCHQ’s existing electronic eavesdropping capabilities.

The surveillance is underpinned by an opaque legal regime that has authorized GCHQ to sift through huge archives of metadata about the private phone calls, emails and Internet browsing logs of Brits, Americans, and any other citizens — all without a court order or judicial warrant

The  Florida Supreme Court has ruled that warrantless tracking of people's location using their cell phone signal is unconstitutional, a move that could have far-reaching consequences and suggests that the most common use of police surveillance tools called StingRays is illegal. The StingRay, if you aren't familiar, is essentially a fake cell phone tower that is used by at least 45 branches of law enforcement in the United States to track criminal suspects (the UK uses them as well). But the way it works—as a cell tower spoofer—means that, by design, all cell phones within a certain geographical area will connect to it, meaning police are sweeping up location information about everyone nearby.

When police have access to StingRays, they use them often: In 2011, the Los Angeles Police Department used it for 340 different investigations; in Tallahassee, Fla., police used them for 250 investigations between 2007 and 2014. Most often, tracking of specific suspects is done without a warrant. StingRays aren't at the heart of Thursday's Florida Supreme Court Decision; warrantless cell phone location tracking is, according to court justice Jorge Labarga's opinion. Nonetheless, the most common use of StingRays would fall under his decision.

In this instance, a suspected cocaine dealer, Shawn Tracey, was tracked in 2007 by police without a warrant. Labarga said this was a violation of the Fourth Amendment. "Regardless of Tracey's location on public roads, the use of his cell site location information emanating from his cell phone in order to track him in real time was a search within the purview of the Fourth Amendment for which probable cause was required," Labarga wrote. No matter where you are, you're giving your location data to third parties: Facebook, Google, all manner of apps you've opted into. But that doesn't give police or the government in general permission to scrape that data or con you into giving it to them, he suggested.

The National Security Agency is secretly intercepting, recording, and archiving the audio of virtually every cell phone conversation on the island nation of the Bahamas. According to documents provided by NSA whistleblower Edward Snowden, the surveillance is part of a top-secret system – code-named SOMALGET – that was implemented without the knowledge or consent of the Bahamian government. Instead, the agency appears to have used access legally obtained in cooperation with the U.S. Drug Enforcement Administration to open a backdoor to the country’s cellular telephone network, enabling it to covertly record and store the “full-take audio” of every mobile call made to, from and within the Bahamas – and to replay those calls for up to a month. SOMALGET is part of a broader NSA program called MYSTIC, which The Intercept has learned is being used to secretly monitor the telecommunications systems of the Bahamas and several other countries, including Mexico, the Philippines, and Kenya. But while MYSTIC scrapes mobile networks for so-called “metadata” – information that reveals the time, source, and destination of calls – SOMALGET is a cutting-edge tool that enables the NSA to vacuum up and store the actual content of every conversation in an entire country.

All told, the NSA is using MYSTIC to gather personal data on mobile calls placed in countries with a combined population of more than 250 million people. And according to classified documents, the agency is seeking funding to export the sweeping surveillance capability elsewhere. The program raises profound questions about the nature and extent of American surveillance abroad. The U.S. intelligence community routinely justifies its massive spying efforts by citing the threats to national security posed by global terrorism and unpredictable rival nations like Russia and Iran. But the NSA documents indicate that SOMALGET has been deployed in the Bahamas to locate “international narcotics traffickers and special-interest alien smugglers” – traditional law-enforcement concerns, but a far cry from derailing terror plots or intercepting weapons of mass destruction.

By targeting the Bahamas’ entire mobile network, the NSA is intentionally collecting and retaining intelligence on millions of people who have not been accused of any crime or terrorist activity. Nearly five million Americans visit the country each year, and many prominent U.S. citizens keep homes there, including Sen. Tom Harkin (D-Iowa), Bill Gates, and Oprah Winfrey.

The Federal Bureau of Investigation is taking the position that court warrants are not required when deploying cell-site simulators in public places. Nicknamed "stingrays," the devices are decoy cell towers that capture locations and identities of mobile phone users and can intercept calls and texts. The FBI made its position known during private briefings with staff members of Senate Judiciary Committee Chairman Patrick Leahy (D-Vt.) and Sen. Chuck Grassley (R-Iowa). In response, the two lawmakers wrote Attorney General Eric Holder and Homeland Security chief Jeh Johnson, maintaining they were "concerned about whether the FBI and other law enforcement agencies have adequately considered the privacy interests" of Americans. According to the letter, which was released last week: For example, we understand that the FBI’s new policy requires FBI agents to obtain a search warrant whenever a cell-site simulator is used as part of a FBI investigation or operation, unless one of several exceptions apply, including (among others): (1) cases that pose an imminent danger to public safety, (2) cases that involve a fugitive, or (3) cases in which the technology is used in public places or other locations at which the FBI deems there is no reasonable expectation of privacy.

The letter was prompted in part by a Wall Street Journal report in November that said the Justice Department was deploying small airplanes equipped with cell-site simulators that enabled "investigators to scoop data from tens of thousands of cellphones in a single flight, collecting their identifying information and general location." The bureau's position on Americans' privacy isn't surprising. The Obama Administration has repeatedly maintained that the public has no privacy in public places. It began making that argument as early as 2010, when it told a federal appeals court that the authorities should be allowed to affix GPS devices on vehicles and track a suspect's every move without court authorization. The Supreme Court, however, eventually ruled that warrants are required. What's more, the administration has argued that placing a webcam with pan-and-zoom capabilities on a utility pole to spy on a suspect at his or her residence was no different from a police officer's observation from the public right-of-way. A federal judge last month disagreed with the government's position, tossing evidence gathered by the webcam that was operated from afar.

In their letter, Leahy and Grassley complained that little is known about how stingrays, also known as ISMI catchers, are used by law enforcement agencies. The Harris Corp., a maker of the devices from Florida, includes non-disclosure clauses with buyers. Baltimore authorities cited a non-disclosure agreement to a judge in November as their grounds for refusing to say how they tracked a suspect's mobile phone. They eventually dropped charges rather than disclose their techniques. Further, sometimes the authorities simply lie to judges about their use or undertake other underhanded methods to prevent the public from knowing that the cell-site simulators are being used.

All across America, from Florida to Colorado and back again, the country's increasingly militarized local police forces are using a secretive technology to vacuum up cellphone data from entire neighborhoods – including from people inside their own homes – almost always without a warrant. This week, numerous investigations by major news agencies revealed the US government is now taking unbelievable measures to make sure you never find out about it. But a landmark court ruling for privacy could soon force the cops to stop, even as the Obama administration fights to keep its latest tool for mass surveillance a secret.So-called International Mobile Subscriber Identity (IMSI) catchers – more often called their popular brand name, "Stingray" – have long been the talk of the civil liberties crowd, for the indiscriminate and invasive way these roving devices conduct surveillance. Essentially, Stingrays act as fake cellphone towers (usually mounted in a mobile police truck) that police can point toward any given area and force every phone in the area to connect to it. So even if you're not making a call, police can find out who you've been calling, and for how long, as well as your precise location. As Nathan Freed Wessler of the ACLU explained on Thursday, "In one Florida case, a police officer explained in court that he 'quite literally stood in front of every door and window' with his stingray to track the phones inside a large apartment complex."

Yet these mass surveillance devices have largely stayed out of the public eye, thanks to the federal government and local police refusing to disclose they're using them in the first place – sometimes, shockingly, even to judges. As the Associated Press reported this week, the Obama administration has been telling local cops to keep information on Stingrays secret from members of the news media, even when it seems like local public records laws would mandate their disclosure. The AP noted:Federal involvement in local open records proceedings is unusual. It comes at a time when President Barack Obama has said he welcomes a debate on government surveillance and called for more transparency about spying in the wake of disclosures about classified federal surveillance programs.

Some of the government's tactics to hide Stingray from journalists and the public have been downright disturbing. After the ACLU had filed a records request for information on Stingrays, the local police force initially told them that, yes, they had the documents and to come on down to the station to look at them. But just before an ACLU rep was due to arrive, US Marshals seized the records and hid them away at another location, in what Wessler describes as "a blatant violation of state open-records laws".The federal government has used various other tactics around the country to prevent disclosure of similar information.USA Today also published a significant nationwide investigation about the Stingray problem, as well as what are known as "cellphone tower dumps". When police agencies don't have Stingrays at their disposal, they can go to cell phone providers to get the cellphone location information of everyone who has connected to a specific cell tower (which inevitably includes thousands of innocent people). The paper's John Kelly reported that one Colorado case shows cellphone tower dumps got police "'cellular telephone numbers, including the date, time and duration of any calls,' as well as numbers and location data for all phones that connected to the towers searched, whether calls were being made or not."

This week the Center for Media Justice, ColorOfChange.org, and New America’s Open Technology Institute filed a complaint with the Federal Communications Commission alleging the Baltimore police are violating the federal Communications Act by using cell site simulators, also known as Stingrays, that disrupt cellphone calls and interfere with the cellular network—and are doing so in a way that has a disproportionate impact on communities of color. Stingrays operate by mimicking a cell tower and directing all cellphones in a given area to route communications through the Stingray instead of the nearby tower. They are especially pernicious surveillance tools because they collect information on every single phone in a given area—not just the suspect’s phone—this means they allow the police to conduct indiscriminate, dragnet searches. They are also able to locate people inside traditionally-protected private spaces like homes, doctors’ offices, or places of worship. Stingrays can also be configured to capture the content of communications. Because Stingrays operate on the same spectrum as cellular networks but are not actually transmitting communications the way a cell tower would, they interfere with cell phone communications within as much as a 500 meter radius of the device (Baltimore’s devices may be limited to 200 meters). This means that any important phone call placed or text message sent within that radius may not get through. As the complaint notes, “[d]epending on the nature of an emergency, it may be urgently necessary for a caller to reach, for example, a parent or child, doctor, psychiatrist, school, hospital, poison control center, or suicide prevention hotline.” But these and even 911 calls could be blocked.

The Baltimore Police Department could be among the most prolific users of cell site simulator technology in the country. A Baltimore detective testified last year that the BPD used Stingrays 4,300 times between 2007 and 2015. Like other law enforcement agencies, Baltimore has used its devices for major and minor crimes—everything from trying to locate a man who had kidnapped two small children to trying to find another man who took his wife’s cellphone during an argument (and later returned it). According to logs obtained by USA Today, the Baltimore PD also used its Stingrays to locate witnesses, to investigate unarmed robberies, and for mysterious “other” purposes. And like other law enforcement agencies, the Baltimore PD has regularly withheld information about Stingrays from defense attorneys, judges, and the public. Moreover, according to the FCC complaint, the Baltimore PD’s use of Stingrays disproportionately impacts African American communities. Coming on the heels of a scathing Department of Justice report finding “BPD engages in a pattern or practice of conduct that violates the Constitution or federal law,” this may not be surprising, but it still should be shocking. The DOJ’s investigation found that BPD not only regularly makes unconstitutional stops and arrests and uses excessive force within African-American communities but also retaliates against people for constitutionally protected expression, and uses enforcement strategies that produce “severe and unjustified disparities in the rates of stops, searches and arrests of African Americans.”

Adding Stingrays to this mix means that these same communities are subject to more surveillance that chills speech and are less able to make 911 and other emergency calls than communities where the police aren’t regularly using Stingrays. A map included in the FCC complaint shows exactly how this is impacting Baltimore’s African-American communities. It plots hundreds of addresses where USA Today discovered BPD was using Stingrays over a map of Baltimore’s black population based on 2010 Census data included in the DOJ’s recent report:

Here’s a recap of Snowden’s leaked documents published so far, in my own highly subjective order of importance.

The Justice Department will regularly require federal agents to seek warrants before using secretive equipment that can locate and track cellphones, the agency announced Thursday, the first regulations on an increasingly controversial technology.The new policy, which also limits what information may be collected and how long it can be stored, puts a measure of judicial oversight on a technology that was designed to hunt terrorists overseas but has become a popular tool among federal agents and local police officers for fighting crime.Civil libertarians have expressed grave privacy concerns about the technology’s proliferation, but the new Justice Department policies do not apply to local police forces.

The device, commonly called a cell-site simulator or StingRay, tricks cellphones into connecting with it by acting like a cell tower, allowing the authorities to determine the location of a tracked phone. In doing so, however, the equipment also connects with all other phones in the area, allowing investigators to collect information on people not suspected of any crime.The device is also capable of capturing calls, text messages, emails and other data. Until Thursday’s regulations, the rules for the use of that information and the duration it could be kept had not been detailed and varied across the department’s offices and agencies.

The first (and thus far only) roll-back of post-9/11 surveillance authorities was implemented over the weekend: The National Security Agency shuttered its program for collecting and holding the metadata of Americans’ phone calls under Section 215 of the Patriot Act. While bulk collection under Section 215 has ended, the government can obtain access to this information under the procedures specified in the USA Freedom Act. Indeed, some experts have argued that the Agency likely has access to more metadata because its earlier dragnet didn’t cover cell phones or Internet calling. In addition, the metadata of calls made by an individual in the United States to someone overseas and vice versa can still be collected in bulk — this takes place abroad under Executive Order 12333. No doubt the NSA wishes that this was the end of the surveillance reform story and the Paris attacks initially gave them an opening. John Brennan, the Director of the CIA, implied that the attacks were somehow related to “hand wringing” about spying and Sen. Tom Cotton (R-Ark.) introduced a bill to delay the shut down of the 215 program. Opponents of encryption were quick to say: “I told you so.”

But the facts that have emerged thus far tell a different story. It appears that much of the planning took place IRL (that’s “in real life” for those of you who don’t have teenagers). The attackers, several of whom were on law enforcement’s radar, communicated openly over the Internet. If France ever has a 9/11 Commission-type inquiry, it could well conclude that the Paris attacks were a failure of the intelligence agencies rather than a failure of intelligence authorities. Despite the passage of the USA Freedom Act, US surveillance authorities have remained largely intact. Section 702 of the FISA Amendments Act — which is the basis of programs like PRISM and the NSA’s Upstream collection of information from Internet cables — sunsets in the summer of 2017. While it’s difficult to predict the political environment that far out, meaningful reform of Section 702 faces significant obstacles. Unlike the Section 215 program, which was clearly aimed at Americans, Section 702 is supposedly targeted at foreigners and only picks up information about Americans “incidentally.” The NSA has refused to provide an estimate of how many Americans’ information it collects under Section 702, despite repeated requests from lawmakers and most recently a large cohort of advocates. The Section 215 program was held illegal by two federal courts (here and here), but civil attempts to challenge Section 702 have run into standing barriers. Finally, while two review panels concluded that the Section 215 program provided little counterterrorism benefit (here and here), they found that the Section 702 program had been useful.

There is, nonetheless, some pressure to narrow the reach of Section 702. The recent decision by the European Court of Justice in the safe harbor case suggests that data flows between Europe and the US may be restricted unless the PRISM program is modified to protect the information of Europeans (see here, here, and here for discussion of the decision and reform options). Pressure from Internet companies whose business is suffering — estimates run to the tune of $35 to 180 billion — as a result of disclosures about NSA spying may also nudge lawmakers towards reform. One of the courts currently considering criminal cases which rely on evidence derived from Section 702 surveillance may hold the program unconstitutional either on the basis of the Fourth Amendment or Article III for the reasons set out in this Brennan Center report. A federal district court in Colorado recently rejected such a challenge, although as explained in Steve’s post, the decision did not seriously explore the issues. Further litigation in the European courts too could have an impact on the debate.

The NYPD has used cell-site simulators, commonly known as Stingrays, more than 1,000 times since 2008, according to documents turned over to the New York Civil Liberties Union. The documents represent the first time the department has acknowledged using the devices. The NYPD also disclosed that it does not get a warrant before using a Stingray, which sweeps up massive amounts of data. Instead, the police obtain a “pen register order” from a court, more typically used to collect call data for a specific phone. Those orders do not require the police to establish probable cause. Additionally, the NYPD has no written policy guidelines on the use of Stingrays. Stingrays work by imitating cellphone towers. They force all nearby phones to connect to them, revealing the owners’ locations. That means they collect data on potentially hundreds of people. They are small enough to fit in a suitcase, or be mounted on a plane.

When they were originally developed in 2003, Stingrays were designed for military use. But in the past decade, they have increasingly been purchased by law enforcement agencies. According to the ACLU, Stingrays are used by at least 59 police departments in 23 states, and at least 13 federal agencies, including the DEA, FBI, and the IRS. Because most departments withhold information about Stingrays, these numbers likely underrepresent the total.

Stingrays have long been a topic of concern for privacy activists. “Cell-site simulators are powerful surveillance devices that can track people, including in their homes, and collect information on innocent bystanders,” said Mariko Hirose, a senior staff attorney at the NYCLU.  “If they are going to be used in communities the police should at minimum obtain a warrant and follow written policies.” Instead, law enforcement agencies have fought to keep Stingrays secret, even dropping criminal cases to avoid disclosing anything about them. The FBI has forced local police agencies to sign Stingray-related non-disclosure agreements, claiming that criminals and terrorists who know about Stingrays could take countermeasures against them. The increasing use of Stingrays, coupled with the lack of transparency, has alarmed civil liberties groups. “I think it’s critical to have transparency about the use of technology like Stingrays,” said Faiza Patel, an attorney with the Brennan Center for Justice. “That’s what allows courts, the public, and our elected officials to weigh in on the proper rules.”

A bipartisan group of 26 US senators has written to intelligence chiefs to complain that the administration is relying on a "secret body of law" to collect massive amounts of data on US citizens.The senators accuse officials of making misleading statements and demand that the director of national intelligence James Clapper answer a series of specific questions on the scale of domestic surveillance as well as the legal justification for it.In their strongly-worded letter to Clapper, the senators said they believed the government may be misinterpreting existing legislation to justify the sweeping collection of telephone and internet data revealed by the Guardian."We are concerned that by depending on secret interpretations of the Patriot Act that differed from an intuitive reading of the statute, this program essentially relied for years on a secret body of law," they say.

"This and misleading statements by intelligence officials have prevented our constituents from evaluating the decisions that their government was making, and will unfortunately undermine trust in government more broadly."This is the strongest attack yet from Congress since the disclosures began, and comes after Clapper admitted he had given "the least untruthful answer possible" when pushed on these issues by Senators at a hearing before the latest revelations by the Guardian and the Washington Post.In a press statement, the group of senators added: "The recent public disclosures of secret government surveillance programs have exposed how secret interpretations of the USA Patriot Act have allowed for the bulk collection of massive amounts of data on the communications of ordinary Americans with no connection to wrongdoing."

They said: "Reliance on secret law to conduct domestic surveillance activities raises serious civil liberty concerns and all but removes the public from an informed national security and civil liberty debate." A spokesman for the office of the director of national intelligence (ODNI) acknowledged the letter. "The ODNI received a letter from 26 senators this morning requesting further engagement on vital intelligence programs recently disclosed in the media, which we are still evaluating. The intelligence and law enforcement communities will continue to work with all members of Congress to ensure the proper balance of privacy and protection for American citizens."The letter was organised by Oregan Democrat Ron Wyden, a member of the intelligence committee, but includes four Republican senators: Mark Kirk, Mike Lee, Lisa Murkowski and Dean Heller.

Help strengthen Oregon's privacy protections and limit the use of dragnet surveillance. We are advocating for:•    SB 339 - Strict guidelines for the use of automatic license plate readers (ALPR) •    SB 640 - A warrant requirement to access email, phone, and location records •    SB 641 - A warrant requirement to search cell phones Advances in technology have made it too easy for law enforcement to track where you go, what you do, and who you are with. Most of the data the government collects is about innocent people who are not suspected of any crimes. Yet the government collects that personal information - or accesses it directly from your internet or cell phone provider – and can keep it for years on end.  Technology has changed but your rights haven't.

The Federal Bureau of Investigation has used a secretive authority to compel Internet and telecommunications firms to hand over customer data including an individual’s complete web browsing history and records of all online purchases, a court filing released Monday shows.The documents are believed to be the first time the government has provided details of its so-called national security letters, which are used by the FBI to conduct electronic surveillance without the need for court approval.The filing made public Monday was the result of an 11-year-old legal battle waged by Nicholas Merrill, founder of Calyx Internet Access, a hosted service provider, who refused to comply with a national security letter (NSL) he received in 2004. Merrill told Reuters the release was significant “because the public deserves to know how the government is gathering information without warrants on Americans who are not even suspected of a crime.”

National security letters have been available as a law enforcement tool since the 1970s, but their frequency and breadth expanded dramatically under the USA Patriot Act, which was passed shortly after the Sept. 11, 2001 attacks. They are almost always accompanied by an open-ended gag order barring companies from disclosing the contents of the demand for customer data.A federal court ruled earlier this year that the gag on Merrill’s NSL should be lifted. Merrill's challenge also disclosed that the FBI may use NSLs to gain IP addresses on everyone a suspect has corresponded with and cell-site location information. The FBI said in the court filings it no longer used NSLs for location information. The secretive orders have long drawn the ire of tech companies and privacy advocates, who argue NSLs allow the government to snoop on user content without appropriate judicial oversight or transparency.

Last year, the Obama administration announced it would permit Internet companies to disclose more about the number of NSLs they receive. But they can still only provide a range such as between 0 and 999 requests, or between 1,000 and 1,999. Twitter (TWTR.N) has sued in federal court seeking the ability to publish more details in its semi-annual transparency reports. Several thousand NSLs are now issued by the FBI every year, though the agency says it is unaware of the precise number. At one point that number eclipsed 50,000 letters annually. The FBI did not respond to a request for comment Monday.

There's been a lot of focus elsewhere concerning the FISA rulings that were leaked, showing that the government is scooping up the details of pretty much every phone call. However, a case concerning some guys who were trying to rob an armored truck may lead to some interesting revelations related to what the government collects. Daryl Davis, Hasam Williams, Terrance Brown, Toriano Johnson, and Joseph K. Simmons were charged with trying to rob a bunch of armored Brink's trucks, in which one of the robberies went wrong and a Brink's employee was shot and killed. As part of the case against the group, the DOJ obtained call records. However, during discovery, the government refused to hand over call records for July of 2010, claiming that when they sought them from the telco, the DOJ was told that those records had been purged. Terrance Brown's lawyer is now claiming that since it appears the NSA has sucked up all of this data for quite some time, it would appear that the government should, in fact, already have the phone records from July 2010, which he argues would show that he was nowhere near the robbery when it happened. Defendant Brown urges that the records are important to his defense because cell-site records could be used to show that Brown was not in the vicinity of the attempted robbery that allegedly occurred in July 2010. And, relying on a June 5, 2013, Guardian newspaper article that published a FISA Court order relating to cellular telephone data collected by Verizon,1 Defendant Brown now suggests that the Government likely actually does possess the metadata relating to telephone calls made in July 2010 from the two numbers attributed to Defendant Brown.

The court agrees that, under the law, the government may need to produce those records. Here, Defendant asserts that, under Brady v. Maryland, 373 U.S. 83 (1963), due process requires the production of the July 2010 telephone records because they are anticipated to be exculpatory in that they are expected to show that Defendant Brown was not physically located at the scene of the alleged attempted Brink’s truck robbery in July 2010. In view of Defendant Brown’s Motion and the requirements of FISA, it is hereby ORDERED and ADJUDGED that the Government shall respond to Defendant Brown’s Motion and, if desired, shall file an affidavit of the Attorney General of the United States. That order was actually issued Monday, only giving the government until yesterday to comply. At the time of posting, the government's reply has not yet shown up in PACER, though it may pop up soon. I'm guessing that they'll try to either get some sort of extension or explain why those records are somehow inaccessible -- but it could get interesting.
