From [HERE] Since 1990, according to Department of Justice statistics, the United States has become a vastly safer place, at least in terms of violent crime. (Drug crime follows somewhat different trends, though drug use has been dropping over the same time period.) The number of murders dropped to 14,827 in 2012 from 23,438 in 1990. The number of rapes has plummeted to 84,376 from 102,555. The number of robberies, motor-vehicle thefts, assaults — all have seen similarly large declines. And the number of incidents has dropped even though the country has grown. 

And there’s no evidence that giving police officers the weapons of war has had anything to do with that decline in crime, either, with researchers pegging it to a combination of factors, among them the removal of lead from paint and gasoline, an increase in abortion rates, and improved policing methods.

So, instead, we get a very militarized police -- and tons of cases where it is being used in cases that absolutely don't warrant it. At all. 

And here's the really disturbing thing. It may get a lot worse. As Vanity Fair notes, on June 19th, Rep. Alan Grayson had offered up an amendment on the Defense Appropriations bill, which would have limited the militarization of police. And it failed by a wide margin. Included in those voting against it? The guy who represents Ferguson.
