I am old enough to remember this event, which should have been a watershed in what not to do.

Instead, naturally as somebody makes a profit at taxpayer expense, like military spending, the militarization of the police only gets more profitable for the wrong people.

The American Civil Liberties Union has released the results of its new survey into the use of Swat teams by police forces across the country. It concludes that policing has become dangerously and unnecessarily militarized, literally so with equipment and strategies being imported directly from the US army.

The findings set up a striking and troubling paradox. The Obama administration is completing its withdrawal from Afghanistan, and the US is on the verge of being free from war for the first time in more than a decade; yet at the same time the hardware and tactics of the war zone are quietly proliferating at home.
