What sorts? You mean the sort that makes threats they can't complete or don't really plan to because they hope to intimidate or have high hopes?

Something more than a drive by remark would be nice.

Any use of lethal force will be questioned. An unarmed man punching you after saying "I'm going to kill you" makes your defense easier. How easy is questionable. If an unarmed man does that to Brock Lesner it is reasonably assumed that he could handle it without a gun unless a weapon is presented. If it happens to Betty White she can proably shoot before or right after the first strike.

I guess some people just don't get the high legal burden involved in shooting another human. It isn't a decision without consequence. Once you shoot your self defense scenario doesn't end. That is just the begining.
