I always try to advocate this fact. A gun is about DEESCALATION. Please be careful, y'all. The gun is meant to get you away, get them away, or get em dead. In that order.
Carrying means added personal responsibility. If anything, it should give a person more reason to avoid conflict. I know it does for me.
The video doesn't show everything and as usual, causes lots of speculation. Shoplifting may not be a capital offense in the eyes of a court, but I won't say I feel sorry for the thief either. Furthermore, I can't see it there was anything in his right hand.
The real moral of the story is don't steal.
