i think the problem has also to do with the kind of people becoming police officers. Not saying that all police officers in the us are that way but there seem to be a lot out there who are just out for violence. Most "rational" people wouldnt want to have a police job. Also becoming a police officer seems to be very easy in most parts of the us - I've even read about a state where your vocational training is as long as two weeks followed by a test nearly everyone could do.It's like the government wants it that way...
