Concluding Thoughts

This case well illustrates both the challenges faced by modern law enforcement in retrieving information it needs to pursue and prosecute wrongdoers, and the threat to the privacy of innocent parties from a vigorous criminal investigation. At the time of Tamura, most individuals and enterprises kept records in their file cabinets or similar physical facilities. Today, the same kind of data is usually stored electronically, often far from the premises. Electronic storage facilities intermingle data, making them difficult to retrieve without a thorough understanding of the filing and classification systems used—something that can often only be determined by closely analyzing the data in a controlled environment. Tamura involved a few dozen boxes and was considered a broad seizure; but even inexpensive electronic storage media today can store the equivalent of millions of pages of information. 1176*1176 Wrongdoers and their collaborators have obvious incentives to make data difficult to find, but parties involved in lawful activities may also encrypt or compress data for entirely legitimate reasons: protection of privacy, preservation of privileged communications, warding off industrial espionage or preventing general mischief such as identity theft. Law enforcement today thus has a far more difficult, exacting and sensitive task in pursuing evidence of criminal activities than even in the relatively recent past. The legitimate need to scoop up large quantities of data, and sift through it carefully for concealed or disguised pieces of evidence, is one we've often recognized. See, e.g., United States v. Hill, 459 F.3d 966 (9th Cir.2006).

This pressing need of law enforcement for broad authorization to examine electronic records, so persuasively demonstrated in the introduction to the original warrant in this case, see pp. 1167-68 supra, creates a serious risk that every warrant for electronic information will become, in effect, a general warrant, rendering the Fourth Amendment irrelevant. The problem can be stated very simply: There is no way to be sure exactly what an electronic file contains without somehow examining its contents—either by opening it and looking, using specialized forensic software, keyword searching or some other such technique. But electronic files are generally found on media that also contain thousands or millions of other files among which the sought-after data may be stored or concealed. By necessity, government efforts to locate particular files will require examining a great many other files to exclude the possibility that the sought-after data are concealed there. Once a file is examined, however, the government may claim (as it did in this case) that its contents are in plain view and, if incriminating, the government can keep it. Authorization to search some computer files therefore automatically becomes authorization to search all files in the same sub-directory, and all files in an enveloping directory, a neighboring hard drive, a nearby computer or nearby storage media. Where computers are not near each other, but are connected electronically, the original search might justify examining files in computers many miles away, on a theory that incriminating electronic data could have been shuttled and concealed there.

From a Ninth U.S. Circuit Court of Appeals en banc ruling in 2010. The Court's holding was that federal investigators had vastly overstepped the boundaries of multiple subpoenas and a search warrant --- and the Fourth Amendment --- by seizing records of a testing laboratory and reviewing them for information not described in the warrant or the subpoenas. At issue in this particular case was the government's use of a warrant that found probable cause to believe that the records contained evidence that steroids had been found in the urine of ten major league baseball players but searched the seized records for urine tests of other baseball players. The Court upheld the lower courts' rulings that the government was required to return all records other than those relevant to the ten players identified in the warrant. (The government had instead used the records of other player's urine tests to issue subpoenas for evidence relevant to those players potential use of steroids.) This decision cuts very heavily against the notion that the Fourth Amendment allows the bulk collection of private information about millions of Americans with or without a warrantor court order on the theory that some of the records *may* later become relevant to a lawful investigation. Or rephrased, here is the en banc decision of the largest federal court of appeals (as many judges as most other federal appellate courts combined), in direct disagreement with the FISA Court orders allowing bulk collection of telephone records and bulk "incidental" collection of Americans' telephone conversations on the theory that the records *might* become relevant to national security investigations. Yet none of the FISA judges in any of the FISA opinions published thus far even cited, let alone distinguished, this Ninth Circuit en banc decision. Which says a lot of the quality of the legal research performed by the FISA Court judges. However, this precedent is front and center in briefs filed with the Ni
