These are pretty much my thoughts exactly. It's impossible to know just what one would do in such a scenario till it actually happens but I'm reasonably certain that if someone was trying to firebomb my house I would shoot them. Consequences of that action wouldn't be at the front of my mind at the time. Same way that if I'm being attacked by a mob self preservation will come first, worrying about the aftermath of my actions will have to wait.Not sure if the first thing that is going to come to my mind is how is the media going to spin my action.
Are the police going to arrest me?
If I am getting my butt kicked or my house fire bombed, my concentration will be on my front sight only.
