With the D.C. crime rate spiralling completely out of control in light of their stringent gun control schemes, the people turn to a somewhat Orwellian solution:
It's not just that a few of them are violent and corrupt, but it's that other cops never seem to call out the others. Even the so called good cops believe in the whole "don't rat on other cops" bullshit. I know if I saw a cop give another cop a ticket like they would anyone else, I'd start respecting them a lot more.
