I have a permit to carry. I would do the same thing in this situation. When the first punch is thrown, I most certainly would feel my life is in danger and protect myself, any way I can. If that means shooting my attacker, I will. That would be the last thing I want to do, but why else would I carry a weapon?
I have had people say to me that the driver of the truck should have driven away [[leaving the scene of an accident)...the driver should have rolled up his window [[did he know the attacker was going to hit him)? Who would expect this person on a bike to get up, after hitting a truck, come over to the driver and start punching?
I hope the police let this man go, he did nothing wrong.
