Not a training related note here, at least not for the IBJJF, but this is a great clip to debrief:
More than any other real world video I've seen, this sets the stage for my argument about why anyone out of a pure striking art should also train in grappling. This might be the worst side control ever established by mankind, yet he manages to hold a cop down who continues to throw ineffective strikes to his attacker.
There's a lot to take out of this video if you're a cop. If you're a martial artist that also holds true.
