I am worried of shotspotter, and surveillance tech. overall, for this project. I prefer the human contact approach. It has precedents, and has somewhat, high ranking officials, from the SJPD, wanting to work this way. Remember the block party idea, around san jose, for july 4? Liability questions may be a problem. But how it can bring community together, can make tech. look like, a cold, isolative, 'turn against your neighbor ' way to work.
