Basically when I watched the video what I saw was a bunch of cowards punching and kicking and elderly gentleman, while another bunch of cowards stood and watched . If this happened in a public place or a city Street would they stand back and do the same ? I'm no super hero nor do I claim to be , but if I had of been present there's only two places I would have ended up and that's either the hospital or a police cell, cause I'm certain I would not have stood back and watched . As the op said sometimes enough is enough. In the words of Kenny Rogers "sometimes you gotta fight to be a man "
