Yes, people will see armed police arresting him for a statement many of them probably agree with and just think it's another example of "wokeness gone mad".

He was arrested in an airport. All the bizzies in airports are armed. It wasn't as if the Met sent an armed response unit to lift him. Incitement to violence is still a crime. If only for the time being.

So who decided it was so urgent and he was such a danger that they couldn't wait until he got home?

He apparently lives in Arizona.
