But it is funny, the lowest of white trailer trash always drive like maniacs, and for some reason act surprised when they get tickets. Funny how that works.
This is not to excuse any excesses by Police - only to give some practical advice. Don't resist, don't run, and for God's sake, don't leap into a Police cruiser and start a tussle.
UPDATE: A friend sent me this link which illustrates why some cops may seem - to lay people - to use excessive force. They are often afraid. There are people out there who want to kill them, often for no reason at all, other than they represent authority. Fear fuels adrenaline, and bad things can happen as a result. So while you may be afraid of the Police, they may be just as afraid of you, which explains why you are slammed to the pavement and then jumped by five people. It may seem excessive, but it has been known to occur that suspects get ahold of a policeman's gun and then shoot them with it.
This fellow in Feurgson leapt into the window of a police cruiser. Do you think it was to change the radio station?
Resisting the Police isn't going to accomplish anything except get you killed.
