President Obama has ordered a White House-led review of federal programs that fund and distribute military equipment to state and local police. Obama cited concern at how such equipment was used during the recent unrest in Ferguson, Missouri, following the police killing of Michael Brown. One of the BearCat armored trucks used during protests there was paid for with $360,000 in Homeland Security grants. According to Pentagon data published by The New York Times, police departments have received tens of thousands of machine guns during the Obama administration, along with nearly 200,000 ammunition magazines; thousands of pieces of camouflage and night-vision equipment; and hundreds of silencers, armored cars and aircraft. Much of the equipment is used by police SWAT teams for what amount to paramilitary raids on people’s homes. A new report by the American Civil Liberties Union examines more than 800 of these raids and found only 7 percent were for genuine emergencies. Nearly 80 percent were for used for ordinary law enforcement purposes like serving search warrants on people’s homes.
