I would consider switching from weapons designed to be used against any innocent person to weapons designed specifically to deal with those looking for a fight to be de-escalation.

A better de-escalation would be to reduce the number of and need for weapons as well as counter hate speech and radicalization. I don't think body armor is going to do the trick, frankly.

(aside: this conversation has jumped the shark IMHO, so this is where I'm getting off. peace, literally)
