It seems to me that a lot less people in neighborhoods like that actually call the police as well.

I've heard the same story of a little kid being left outside, in two different neighborhoods, with a vastly different result. In the poor neighborhood, the kid was in his diaper (only), sitting on one of those electrical boxes, in the rain, for more than an hour, crying. The person who told the story said he eventually went to the parents house and told them to go get their kid.

In the nice neighborhood, the drunk loser father was asleep in the basement, and the little girl got outside and was playing in the yard across the street by herself. In the nice neighborhood, the cops showed up in minutes, picked up the little girl, and drove up and down the street asking where she belonged with the loud speaker.

Maybe the cops in bad neighborhoods have less to do? Maybe the nice neighborhoods are more sensitive to crimes? I don't know.
