Moosulman,
I remember years ago watching CNN where a small group (2-3 individuals) attacked a former Olympic Team Judoka in a small convenience store he owned in New York.
The funniest thing that I remember is that the owner of the store refused an interview, but they did show one of the attackers on an ambulance gurny being shoved in the back of the ambulance.
I still smile at that.
And, OK, my experience: I was instructed by a fourth dan BB in judo. He won a BJJ tournament, heavy weight BB division in Dominguez Hills, CA. I believe it was 2002.
I have seen him manhandle purple belts and brown belts in BJJ. I have also known him to loose by points in another BJJ tournament at BB level. But no one is perfect.
All, I am saying is that the guy was good. Doesn't mean every Judoka is going to be that good, but that to dismiss outright all of Judo is foolish.
Judo can be phenomenal. I like it, don't practice it now, but I try not underestimate it....and never dismiss it for real, self-defense use.
