You may very well be ethically correct...but the law in Pennsylvania says that if the perps are fleeing, you’re not allowed to shoot them. That’s the case whether we like it or not.
As a CCW holder that rarely goes unarmed, I believe that it is neither legal OR ethical to shoot someone that is not directly threatening your life.
This guy was wrong. Period.
Do you have a source for that?
I know that is not the law in Bucks County, Pennsylvania.
