Of course not. I am an armed citizen and I would first threaten and then use deadly force if required.I would do so without passion or prejudice.
And I still wouldn't be angry. I might be pumped up on adrenalin and excited as hell...but not angry.
By the way...what makes me angry and mad as hell is that looters have not been shot on site(sight). Now that pisses me off.
Oh, I see. From your original post I thought you meant no one should be angry about the looting and violence. Thanks for clarifying, and I'm sorry for the misunderstanding.
