The guy who damaged my leg did some judo shit - a big hip, I think. It's completely against the rules, so I wasn't prepared/didn't know how to fall (though if it wasn't so strong, nothing would probably happen to me). This is the problem with training in London: the risk of crossing some random idiot on the mat. And he wasn't even punished for that.
Were you doing judo? Where? As I mentioned., try Budokwai. Roger Law wrote a book about the club and relevant anecdotes.
This is a good way to train. All about technique. I've lost count how many times I've thrown by WR.

I've being judo since 1972 but these days beginners and experts are on the same mat.
1. Teachers are afraid to warn students because of lost revenue and because confrontation in Dutch culture is taboo.
2. Spirit of judo has gone to the dogs, no give and take, even with sparring.
3. You learned from each other in the past. No beginners, that a separate group.
In our classes I use 60% of my strength on belts lower than black. Above that 80% because you don't get injured.
