I don't think you understand what "de-escalation" is. It's not ignoring antisocial behavior or failing to confront people.
I'm claiming that some antisocial behavior is only triggered by some degree of escalation.
It would be violent crime trend correlation with de-escalation training. Or even with complaints of police aggression.
Even more useful would be to separate out assault + battery where the victim is random vs. non-random, IE domestic or gang.
