If you attack me, I will do whatever I have to do to keep you from doing so again. Anything else is foolishness. You and I weren’t there, so we don’t know how threatened he was or felt himself to be. The youngster should not have robbed a business. He’d be alive today if he hadn’t. I feel no pity for him, at all.
It’s obvious watching the security camera he didn’t feel threatened after the assailant fell to the floor.
