6 charges of soliciting murder – this law is probably OK. It’s an abridgement of free speech, but a long-standing and fairly reasonable one.
Also 4 charges of “stirring up racial hatred”. This is an unacceptable abridgement of free speech. In practice it’s much easier to stir up hatred against yourself than against others, and Hamza is responsible for more hatred of Arabs than of Jews. Of course, since he wants war, that’s all OK from his point of view, but it’s pointless to ban it.
Finally 1 charge of possessing information of a kind likely to be useful to a person committing terrorism – you always feel that law has to be a joke, but it isn’t. Terrifying.
The Americans want him on a whole bunch of actual terrorism charges. I’d much rather see him done for that.
