There just aren't enough cops to go around. Why is it that someone else always has to clean up your mess. Get your neighbors together and start cleaning up your own streets.You are not going to get citizen support when you tell them to move out, do your job or quit.
I was told the same thing a few years ago and it made me very angry so I filed a complaint.
This is not me being racist, this is me being real. When the blacks move in, the neighborhoods go down. It's a known fact. Clean up your own mess.
