UKIP marched to Downing Street under a Ninth Crusade banner. The Met arrested four counter-protesters and no marchers.

Criticism of Islam is protected and must stay protected. Abuse shouted at Muslims to frighten them is a religiously aggravated offence, and the power to deal with it already exists. What does not exist is any published standard for when police use it at a demonstration. Ask your MP, the Mayor, the Met and the Home Secretary to publish it, and to say what was assessed before UKIP marched.
