Yes, a person dont have to kill someone just cause they can to stop a threat.
When I was a bouncer I couldnt hurt the person I was dealing with, no matter how much Iwanted to. So I learned how to make a person walk with me
right out the door. Come back tomorrow after you sleep it off, hurt him? Heck no he is a customer and spends a lort of money he just had too much to drink.......
