I belong to a Neighborhood group, and I've made them aware. There are people on there who are trying to get everyone to have front porch lights on, because lighting up the block is a deterrent in itself. I'm the only one on my set of row homes who has a porch light on all night. It's extra money, but for the pennies it costs, I think they are worth it.

I also report any thefts or destructive behavior to the police. They been cracking down on graffiti, drug and gang activity(they are all connected) but these other things just seem to get brushed under their rug.
