Having been a proud member of the LAPD for 30years. And also having been a folkie since the 60's (oxymoron huh like military intelligence) and having never killed anyone and having carried a gun for 30 years and it never killed anyone either. I have a different take on cops. Cops can and do contribute to the political process as long as they are not in uniform, having said that, if your a cop marchin in a peace march, being policed by your own department you just ain't to darn smart. Let's say some innocent protester starts throwing bricks(which by the way hurt like a SOB),and the off duty cop gets caught in the middle, so he has to explain to his department what he was doing at the riot. And he gets fired and his family leaves him and now he can go to any march he wants cool huh. But now I'm retired so I can go to any march I want.
