Amid widespread criticism of the deployment of military-grade weapons and vehicles by police officers in Ferguson, MO ... NPR obtained data from the Pentagon on every military item sent to local, state and federal agencies through the Pentagon's Law Enforcement Support Office - known as the 1033 program - from 2006 through April 23, 2014. We took the raw data, analyzed it and have organized it. We are making that data set available to the public. The 1033 program is the key source of ... military items being sent to local law enforcement [such as] mine-resistant, ambush-protected vehicles, or MRAPs. More than 600 of them have been sent ... mostly within the past year. The Pentagon has also distributed: 79,288 assault rifles, 205 grenade launchers, 11,959 bayonets, 3,972 combat knives, $124 million worth of night-vision equipment, including night-vision sniper scopes, 479 bomb detonator robots, 50 airplanes, 422 helicopters, [and] more than $3.6 million worth of camouflage gear and other "deception equipment." The list [also] includes building materials, musical instruments and even toiletries. Congress authorized the 1033 program in 1989 to equip local, state and federal agencies in the war on drugs. In 1996, Congress widened the program's scope to include counterterrorism. The data do not confirm whether either of those public safety goals are, in fact, driving decisions.
