I really abhor this video. I don't want to start a flame war against ARMA, because that's not my intent, but this video is on their main site with their feature videos, supposedly as a good example of how rapier is all about "do whatever it takes to survive". If someone pulled that crap at VAF, where he was willing to injure a partner during free fencing in order to win a point, I'd kick his ass out, and he'd never be welcome back, *period*. And you can be sure Alex would back me up for doing that.
I hate that kind of BS behaviour. When you fence with a partner, you are putting their safety into your hands. You are entering an agreement with them that, while accidents happen, you are going to do your best to stay in control of yourself. Injuring a partner (not an enemy!) bad enough that he has to drop on the ground in pain is a sign that you have no right to use a sword. Its also a perfect example of what outsiders point to when they say people like us are out of their mind and are a danger to society.
Sorry for the rant.
