I'm curious to know what statute was invoked in the arrest. I mean, does Britain really have laws against racist speech or behavior which doesn't ostensibly infringe on another's rights? If so, wow. Seems that the codification of political correctness is much further along on the other side of the pond...
And even if they do have such laws, I'm almost certain they're not applicable here anyway. For once -- and in the most bizarre situation to do so in -- they must have decided to follow the spirit of the law rather than the letter, because I'm damn sure that there's no specific law prohibiting asking out of a group at school due to communication issues. What a joke.
