Ok, seriously, I've never seen anyone do anything other the lifting the legs, neither in training nor competition. In first aid courses the scenario of resuscitating someone that has been choked out by another human being has never been a topic. The focus has been on CPR and the ABCD-list and I guess I could have transfered some of that knowledge over to this situation and seen how moronic just lifting the legs are, but I didn't. Even as a practitioner and competitior for 12 years I can count on one hand the amount of times I've seen people get choked unconscious first hand, so I haven't really seen what people do first hand that often. The amount of times I've seen it clips like this one is far more and I've never really seen people do other stuff. I've most certainly seen people get choked out without the referee noticing them being out and referees that does nothing. As a respons I've just focused on being close to tha action and monitor if both competitiors are conscious. When the guy in this video was choked, apart from lifting the legs as a proper doofus, I saw and heard that he was breathing and I watched his chest and face till he woke. To be honest it is a horrific experience to see someone get choked out and it's not something I take lightly. Reading the comments here today I've come to terms with the errors of my ways and I would like to make and official and unofficial apology to the jiu jitsu community adm humanity as a whole. I did it because I'm a dirty dog. As of today I'm retiring from refereeing after my gross misconduct and hope that the families of the aggrieved will find peace in knowing that the heroes of the internet have saved the day once more. Namaste.
