The kind of commnuity involvement you are talking about is way beyond the level of neighborhood watch. Listen I cut my teeth on the streets of detroit, went to public school there, and in the end everyone of my extended family became statics of crime in one fashion or another, in every case we reported there crimes to the police in every case there was no resolution. There's come a time when the personal cost on quality of life is too much to bear. I have family and friends who are still firefighters in the city and all I ever hear from them is how bad it is i.e. 90,000 vacants even if the number is 50K that is insane! Call me what you will the truth is its a losing battle.
