For what it's worth I prefer independent cops. No one knows who is a cop, or who's just trying to cover their own ass. It lends more paranoia to the proceedings, which is what I find enjoyable. Then again I also really liked the Fragile Alliance multiplayer concept in Kane and Lynch, so I might be in the minority. I also killed 7 of my teammates in a 8 man game, the maxium number allowed, just to say I did. Even though I realized I'd never escape when they respawned as cops. I'm just that kind of guy.
