You cant go into an old established institution like a Police Department and effect change as much as you'd like.

In theory its great to have people from the community come in and serve. I was thinking about all the educators I know - who in theory would make good community policemen/women.

The problem is once they're in this current system of police unions and old school establishment - its hard not to get sucked in at some point. Im not saying there arent good officers that try and do good work - but when youre a part of a fucked up racist system thats long established that's bigger than you--at some point(s) in your career you become a part of that system.
