“if they themselves are not a violent criminal, yes.”
IMO, if they manage to take the weapon and kill the attacker, they should get to keep the weapon, and put the attacker’s head on a pike in their front yard as a warning to others.
no, not if thgey too are a violent criminal. this is why criminals can’t claim self-defense if they are involved in criminal activity and somehow try to claim self-defense. doesn’t work if you’re a thug.
