Yes. And those who had to deal with these situations do have useful experience. Whether it's the actual fighting technique depends on a few factors (their success, their ethics, etc.), but they certainly should be able to shed some light on the things you referred to.Is it possible that in some tough neighborhoods, street fights are more a matter of course?
I'm not talking about two idiots trying to prove their manhood, I'm talking about a guy in a bar in a tough neighborhood, who can't talk down a drunken bully, so he has to defend himself?
If so, is it possible that the guy can teach us a bit about how drunken bullies behave, for example, when they mean it, when they don't?
