My friend, who lives in another state, was at a casino last weekend and was randomly jumped by three latino gang bangers. Apparently the surveillance showed these three punks randomly shoulder checking guests just looking for a fight. They stepped up to him at a slot and was calling him on while throwing up gang signs in his face. Of course, he wanted nothing to do with it but they jumped him anyways. As they were arrested they found knives on all three punks. In that situation, out of the freaking blue, what would you do?
Not much more you can do but protect yourself and hold off until security comes. Of course attack their balls, no shame in that, in that situation.
If it's 3 on 1 and I think my life is in jeopardy? Well it's extreme, but I'd probably make sure I grabbed one by the throat, sunk my fingers in and ripped his larynx out. Then it's 2 on 1 and that's a sporting chance.
you had best make sure that you kill him or risk being sued. Never just disable, maim or blind, make them dead.
What would I do? It depends. In a casino I know help will arrive pretty quickly so I'd fight it out and take my lumps. But if I were on some dark deserted street I'd just try and survive and hope I get revenge some time soon.
