lol you're retarded. I'd argue with you but there really is no point.
I've seen my share of bad shit go down in cities around the US. Its miles better than half of the rest of the world. NYC is the shit, stop rotting your mind with video games and go enjoy everything available to you.
Also... most major cities have quotas for their police. There are always douchebag cops, inner city police work isn't the most attractive job so you don't get the "finest" employees either.
