I did watch it, and he belittled Jake's black belt, then used a classic carnival huckster tactic where he did a public demo under his terms and rules (the old: "Ah yes, but what if I did THIS?"). Again, it's not that Rickson's techniques are invalid, it's the sales message he and his family push that A. "Self Defense" is defined as we define it; and B. If you don't follow OUR system for "Self Defense" then you are unprepared for da streetz, even if you are a black belt like Budo Jake. There's loads of textbook marketing schtick going on here, and it has little to do with Rickson's valiant (if embellished) fighting history or his fascinating invisible jiu-jitsu theories.
