Al-Qaeda ‘groomed Abdulmutallab in London’

Grooming takes place all the time here in the UK while the government does nothing.

"He is the fourth president of a London student Islamic society to face terrorist charges in three years. One is facing a retrial on charges that he was involved in the 2006 liquid bomb plot to blow up airliners. Two others have been convicted of terrorist offences since 2007. "

So, why doesn't the government shut down the London Student Islamic Society?
