This is one of the worst kinds of A-holes to me. Not only was this juvenile and crazy, it was very very dangerous. Utah, I believe, has one of the highest concentrations of CHL holders and this could have caused one of those mythical, road rage, blood in the streets confrontations to actually happen. I hope he gets quite a few years for his stupidity. I also hope that all instructors use this story as a perfect example of what to not ever do.
