I believe the boys reaction to this SOB is a by-product of post-modern educational philosphy presented in most public schools. "Group think" is highly valued. Individual responsiblity is down-graded. Lessons in value clarification teach self-interest is superior to self-sacrifice.
I just love the Holywood bravado on this thread - the arm chair heroes that were not there. Just for the record, for those who complain about whimps - my karate masters, one a well-known welter weight champion, the other ex-secret service - trained troops in Desert Storm etc. tells us don't argue with a gun - you will lose.
