In prison? Depends on who you're stuck with. I'd say that they give you at least somthing in your toolbox that the average Joe wouldn't have, but that is about it.
In prison or in the real world. Now, while I don't think that everyone that tries to mug us on the street is a trained MMA fighter, and while we may think of them as the average Joe, I still don't want to under estimate them. For all I know, they could've spent the last 10yrs behind bars, now they get out, and go right back to robbing people. So, in essance, this guy is no different in his mentality than the people who're still locked up.
Interestingly enough, I mentioned this clip to my Kenpo inst. today, during my lesson. We worked some Kenpo and Arnis knife work. Some techs. better than others, but then again, we found ourselves having to modify things for a more aggressive type stab.
In prison, and I speak as one never having served a prison sentence nor having worked in corrections, I think that being aware of your surroundings, the politics, and doing your best to steer clear of trouble is more important than technique and training. When those things don't work, technique and training are good things to have, but they're just tools.
Really the best bet is to do your best to steer clear of trouble on the outside and do your best to not end up on the inside. The biggest disadvantage that the average MA student has in prison is that they're not going to be accustomed to the environment, which can get them hurt or killed.
