How do the cops on SVU keep their jobs?

[erisi236]

I really have to wonder this, I watch Law and Order: SVU quite a lot and there isn't a single episode where one of the Cops doesn't brutalize a suspect or break the law themselves in order to get a criminal. If that isn't enough the Single Female Lawyer often breaks Court rules to win convictions against people,

All of them have been "called into the office" of The Chief of Police or brought up before the Bar to face charges, but they always skate.

Is this just a sad commentary on our modern Justice system or what?

IT'S BECAUSE THEY GET RESULTS!

Because Det. John Munch has incriminating evidence against the government on the existance of extra-terrestrials after his meeting with The Lone Gunmen.
