Law Enforcement officers of my era would be jailed for the way we dealt with this type of trash. Back in the day we shot cars that ran roadblocks. We didn't holler tazer-tazer-tazer, or however down with pepper spray.
We told'em we'd quit Hit'em when they quit fighting. Pull a knife? BANG! A hammer, or club? Bang! Beat he'll outta a woman, a kid, or the elderly? Please resist arrest.
It was a quieter time.
