Hey, man - if you are a good enough shot, caliber and ammo are almost irrelevant. Head or heart shot will do the job......
Kudos to this bystander - most wouldn’t get involved - especially after the fact.......
The only guaranteed one shot stopper is to the CNS by a caliber and bullet designed to penetrate there. Under duress, most shooters are lucky to be able to pull that off.
This guy was remarkable. There also are on record many instances of head shots not taking someone out of action.
I wonder what the laws in Pa are for action taken by bystanders? I hope this guy is not hounded by the police or the families of the poor deprived felons who met their just ends.
