Yea, I was very surprised to hear that! It's a crying shame; glad I don't live in London. On the other hand it goes back to the ancient history of martial arts like jujitsu and karate. When the ruling clans outlawed swords people turned to martial arts. (gunpowder wasn't invented yet) The ruling clans then tried to outlaw martial arts techniques and people began to study in secret. No wonder the U.K. martial arts culture is so big. History repeats itself.
