Well the BNP guy who marched at the head of the police demo - Richard Barnbrook - their mayoral candidate, must have cum in his pants to be leading a march of (virtually) exclusively white folk through London. I saw about 3 non-whites on the march as I watched it file past. Reckon there was about 20,000 so a normal police estimate would have that as 5,000.
Barnbrook claims he was welcomed by the police federation who deny inviting him, but accept that they didn't ask him to leave. He marched at the front and 'BNP TV interviewed numerous cops who were all too happy to associate themselves with fascists.
