Whoa, whoa, take it easy on me guys. I'm a recovering liberal, geeze.
The question asked was not "Would you shoot?" but "Would you be within your right to shoot?". Would I shoot? Like I said above, with wife and kid in the car, abso-#$%@ing-lutely. Without? Not right away, but I'd certainly feel justified. I like to look at things from every side, and play devil's advocate. I know there's no time to do that on the spot, in the field, when the chips are down, so that's why I try to do it here, and beforehand, to guess how I might react.
And as far as getting out and confronting him, in this case I wouldn't be too worried about it (assuming I had something with which to defend myself.) Against a group of 3 or more? Certainly not. Again, I was just answering the question posed, not trying to pussy out of shooting. To my point of view, he did not seem to be very threatening (to the people inside the vehicle), moving around the car and hitting the car. Looked more like he was trying to make a point.(I couldn't understand a thing he was saying in the beginning of the video) Of course, this is all well and good to say in the security of my own home. Doubtless I'd feel more threatened were I sitting in the car while someone beat on it with a crowbar.
My honest feeling is I hope to never find out, but plan to carry just in case I do.
