Per The Daring Dufas:
So why don't the British magistrates pull Islamic Fundamentalists into
court over their teaching that nonbelievers should be killed? It may
have something to do with the fact that the Muslims will kill them?

I'm no lawyer, but reading the OP's link I come away with the impression
that fraud has to involve enrichment of the perpetrator at the expense
of the victim.
