So you think the police were responding to ShotSpotter alerts and bringing people hamburgers?
We already know "aggressive law enforcement" reduces crime. If you put enough young men in prison for loitering, marijuana, and other victimless offenses, crime will go down because you have accidentally arrested a few would-be violent offenders.
But that's insanely unjust and expensive, so people pitch us things like ShotSpotter to make cops smarter.
I have a vague memory of some quote about "if you want to solve crime, keep young men off the streets until they're 25 and you'll have eliminated 90% of crime but that's not a workable policy" (and about 90% of traffic accidents, I reckon.)
