I too think he's sane and think herecomesthesun explains it the way I would have if I'd have thought of it first.
As for the trial: it does have to be reported or do we want to live in a place where there are secret trials and no details of death because it's upsetting, sordid or inconvenient?
We could live in China and ignore the curious case of Neil Heywood or in Britain with the no less unexplained death of the MI6 worker Gareth Williams 
The judge (or tribunals in other countries) ought to be able to step on any grandstanding, as has happened here in the case of the banning of his self-styled salute.
But people have to be allowed to speak their piece at trial. Some of them might turn out to be innocent. For the rest of them, however repugnant their views, I want to ensure they get a fair one and never get the chance of an appeal on the grounds of an unfair hearing.
The only people who have the right to be repulsed by this are the family and friends of the victims. For the rest of us it's merely offensive. I guess most real victims would say it was the lesser of two evils.
