Authorities evacuated hundreds of students in an orderly procession - a demonstration of aggressive security measures developed by police and schools following the chaotic 1999 shooting at Columbine, some 8 miles west of Arapahoe High. After that tragedy, police across the country developed "active shooter" training in which responding officers rush toward gunfire - and step over bodies and bleeding victims if necessary - to stop the gunman.

Gary Sommers has over 40 years service in law enforcement first with the Prince George's Police Department and now with the Montgomery County Police Department both of which are in Maryland. It was while he was working on the Prince George's County SWAT Team in 1988 that Gary was involved in a Blue on Blue shooting that resulted in the death of his best friend and partner, Sgt. Mark Murphy.

Are these 'expert' users at higher risk because of a false sense of security, or because they are naturally curious and therefore more risk-tolerant? Two Polytechnique academics apply clinical trial method to the design of a first-of-its-kind study on computer security.

A new Pittsburgh police program will try to connect domestic violence victims with resources to reduce the risk of more violence, police leaders said on Friday. Beginning Monday, officers responding to intimate partner domestic violence calls will ask the victim 11 questions meant to gauge the potential for homicide or serious assaults in the future, Acting Chief Regina McDonald said at a news conference at headquarters in the North Side. Officers will use a department-provided cellphone to call the Women's Center and Shelter of Greater Pittsburgh hot line to put the victim in touch with an advocate if they determine the victim is at a high risk of further trouble.

May there never ever be another Sandy Hook. However, if the situation arises where first responders need to address an active shooter, we want them to be ready. After taking part in Urban Shield, the hope is all tactical teams will use radio communications effectively - allowing connected teachers and tactical teams to enable the fastest response possible to keep students safe.

What each of these stories have in common is that they all arose in states-California, Massachusetts and New York-that do not have laws governing the licensing of law enforcement officers who engage in serious misconduct. Thus, it is up to each department to decide whether to apply discipline-and what kind of punishment, if any, is merited. Similarly, New Jersey, Hawaii and Rhode Island have no police licensing rules. The remainder- 44 states-do have the authority to remove the licenses of unfit police officers.

The FBI has helped to disrupt or prevent nearly 150 shootings and violent attacks this year, in part by steering potential gunmen toward mental health professionals.

In the year following the Newtown tragedy, police have reassessed the way they'd respond to a similar incident, and a number of departments are learning how to better work with people who have mental health issues or are in crisis.

While 86 percent of Americans now wear seat belts, an upcoming study that will be published by California's Commission on Peace Officer Standards and Training estimates that roughly half of law enforcement officers don't wear them.

Only 4 percent of people who hold degrees in computer and mathematical sciences were employed by the government as of 2008, the report says, compared to 70 percent in the private sector. The lack of talent comes from substantial recruitment and retention barriers.

Allan Friedman, Austen Mack-Crane and Ross Hammond say they developed a preliminary model to look at the long-term consequences of data theft on diverse economic sectors. Their approach depends on treating cyber theft not as a problem of stolen assets worth an intrinsic value, but as one of diminished future growth. When so framed, the effect that stolen data has on companies within a sector--the ones the preliminary model investigates are the chemical, pharmaceutical, financial, consumer mobile phone and semi-conductor industry--depends on what type of data is stolen and the competitive nature of those sectors.

Your firearms and equipment are the lifesaving tools of our profession. Their functionality and reliability should be without question or hesitation. Your safety should never be compromised.

"A chief of police has two important and sometimes conflicting responsibilities - his or her own officers and members of the community. He or she must, on one hand, be the leader of the police  and, at the same time, the chief of and for the community. It is in the use of deadly force that these responsibilities come into conflict. If the chief, in a questionable shooting, decides in favor of the officer, the chief must be able to demonstrate to the community and convince them that the shooting was both lawful, within the stated policy of the department, morally defensible, and consistent with training."--David Couper

In March 2011 the Hawthorne, California, Police Department Community Affairs Unit hosted their first Coffee with a Cop event. Police and community members came together in an informal, neutral space to discuss community issues, build relationships, and drink coffee. Just two years later, Coffee with a Cop events are being hosted in more than 36 states across the nation.

It's a simple concept. Police and community members come together in an informal, neutral space to discuss community issues, build relationships, and drink coffee. In over 175 cities and towns in 36 states, Coffee with a Cop has done wonders for community trust, police legitimacy and partnership building.

As of December 10, 96 officers have been lost in the line of duty. The "Silly Season" has arrived, when risk seems to escalate. Frank Borelli compiles a list of tips to keep brother and sister officers alive.

Last month, a group of retired senior-ranking officers argued before a packed audience at the Capitol Hill Club that despite the near certainty of shrinking military budgets, there are ways to trim the Defense Department's spending without leaving the armed forces less-than-ready for combat. Their plan, they contend, could reduce the overall size of the military while actually increasing its combat power. And in doing so, it will support Secretary of Defense Chuck Hagel's call to revamp the military so that it remains sufficiently strong "under a cloud of budget restraints and uncertainty."

A team of heavily armed New York Police Department officers conducted a late-night drill at a closed shopping mall last month in hopes of avoiding a repeat of the chaos that accompanied the mall massacre earlier this year in Kenya, police officials said Tuesday.
