PHOENIX — Military-style semiautomatic rifles have been used in at least four high-profile shootings in the past year. Bushmaster variations of the weapon have been used in two recent attacks, including the Newtown, Conn., school shootings and the Christmas Eve ambush slayings of two New York firefighters. While commonly called the AR-15, Colt and Armalite have been the only companies to make weapons by that specific name. Many other manufacturers, however, now sell similar versions of the rifle largely styled after the military's fully automatic M-16.

Tempe police are asking for the public's assistance in locating an AR-15 rifle that was stolen from the personal car of a SWAT officer early New Year's Day, and have launched an administrative review into the officer for any potential weapons policy violations.

Orlando Hotusing was serious about public safety. Flashing a badge and identification card, police say the 48-year-old identified himself as a federal air marshal, patrolling his Mesa apartment complex, performing traffic stops and once getting into a vehicle pursuit.

It’s only human nature to want to take action after such a harrowing traumatic event. To do something. Anything, to protect our kids. And make sure that Newtown never ever happens again. Here. There. Anywhere.

So the President released his list of executive orders and suggested legislation last week — nothing surprising there, given the President’s previous comments. None of them will stop a madman from killing. Even the President recognizes that. But they might diminish the amount of carnage the madman can inflict. And if we’re lucky, might even prevent him from carrying out his murders.

A year has passed. The outrage has subsided. The public outcry for change has faded. But the slain are still deceased; the wounded are still trying to recover and lives and families have been damaged forever.

Floyd and Mary Beth Brown: These liberal media elites outraged by gun-bearing citizens showing up at Obama events have probably never used a gun in real life. Most Americans don't see firearms as a symbol of violence. Like our founding fathers, they see them as a tool for personal protection.
