Excellent point MM. From what I have read on this thread, it seems obvious that these thugs got a kick out of roughing up people whom they thought were unable to defend themselves. The thugs were wrong in this case, and I, for one, am glad.
I am reminded of a very old joke:
A man who was offended by some comments from a trucker on his CB confronts said trucker at a rest stop:
Offended man (striking his best martial arts pose): "Karate!"
Trucker: "Tire tool!"
Guess who won that fight.
LOL I know a version of that joke.
