I'm a little late here but.....
I will agree with you 100% here. Fact is, crowd of people or not, NO ONE was acting in any way to stop the altercation. It would have been very easy for a few people to stand in front of him and ended it right there, but the fact is no one bother to do much more then tell ZO-puss that it wasn't worth it.
Let me tell you a little story...
A few years back, I had a friend that was mugged by a group of guys that decided to take advantage of their groups numbers. My friend was carrying, and decided to 'man up' and try to just fight them away instead of using his legal right to bear arms. Fact is, he took one hit to the back of the head and never regained consciousness. The low lives left him to die in the gutter. He was in a coma for a week before he finally died from head trauma.
With that said, if I'm carrying and someone decides to attack me, it's fucking done right there. I've got a long life to live, and I'm not playing around anymore. You guys can call the pussy card all you want, but you never know if you're gonna get hit, stumble, and smack your head on a curb/car/etc and it be over with right there.
If someone's gonna take the time to attack a man walking away from a fight, they better be ready to pay. Whether it's a shot to the chest or a shot to the knee.
