A number of recent homicides have obviously been gangsta' style killings in less densely populated suburban areas; the Stuckagain Heights and one on the Hillside recently come to mind.   Clearly, these crimes occur where they do because there is less chance of observation in those areas.   There is clearly a high correlation between the presence of Section 8 and other low-income housing or homeless camps and crime in that area, but there isn't necessarily the same correlation between crimes discovered in other areas.   Somebody once said you robbed banks because that's where the money was, well, you commit crimes in some areas because that's where the cops aren't.
