The crowd were not searched for weapons before the demo started, which was a serious misjudgement. Some of the missiles contained exploding marbles, several of which were reported by observers to have struck an officer on his backside, which might have been the result of the one solitary arrest. One thing is for sure - the neo-nazis were allowed to publically incite racial hatred by waving an SS-banner and make umpteen Hitler salutes.
The SS insignia is illegal in Germany, and should be likewise in the UK. Making the straight-armed salute in public should be a criminal offence under UK law, and should be enforced with jail sentences. At a time when anti-Semitic violence is at an all-time high, open support of National Socialism is making life extremely dangerous for Jewish and other minorities.
Yet the NWI and the NF were doing what they liked without the cops caring less, antifascist observers were being filmed non-stop by the OB.
