Why are you here speculating so wildly?
I could hazard a guess, but not being blessed with the gift of telepathy, I could of course be wrong.
Still, at least the wild-straw-grasping is keeping the thread bumped.
And it's pretty clear to anyone who watches the videos - even if only the shorter of the two rather than all of Posie's life feed (in the OP) that something is very, very wrong with this as a piece of policing.
Anyway, worth posting the shorter of the videos again (only 3 minutes 16 long)
so that people who are interested can watch it and make their own minds up.
And remember: even if you disagree with Posie's views, the question you should be asking about is do you want your rights to express a political opinion suppressed in this way? Because that's the thing about the law and about policing - they should be applied, impartially, in the same way to everyone. So if the police think this is okay wrt to Posie's demo, they should think the same way about all demos.
