That's a very good question.
If I would mention one of the challenges we have in smart policing and policing research generally, it's the cost-benefit piece. Boston has not conducted, or at least has not published to my knowledge, the cost-benefit analysis of that part of their work.
We know of several studies that have been done and if the committee hasn't come across them, then I would be happy to provide them. There have been several studies done on the cost of policing and the cost of criminal justice processing for different types of crime. I actually made a few notes about that and these costs range greatly.
One study estimated the cost of a murder at $1.4 million, and another study estimated the cost of a murder at $8.6 million. The implication is if you reduce your homicide rate by 10%, you're potentially introducing $10 million, $20 million, $30 million in savings. But this methodology is not quite refined yet. It's hard these days to put a good confident cost figure on these crime reductions.
