I can see why someone like you would enjoy such a thing.
on a side note I'm not a fan and never will be a fan of bjj. I don't believe your average shmuck walking down the sidewalk should even be able to be taught such a lethal art of combat. Only police/military should have this type of training, otherwise some tool like you yourself can actually hurt an upstanding citizen whom actually contributes to society.
and this is coming from someone who stopped one belt short of a black belt because I didn't wanna get myself registered. I took 4 years of classes, 8 months of those were from a world champion 4 days a week... so it's not like I actually hate martial arts, just bjj.
