I'd regard a van load of heavy wooden signs as potentially offensive weapons! I'd also be pissed off if I had some dickhead screaming through a megaphone and blocking my view in front of me.
We live in a democracy. Fuck off and vote. Set up a republican party. Don't intimidate other people. I would find a bunch of screaming fanatics intimidating.
Sigh.
It was agreed by the Police Liaison Committe over months where they would stand, not blocking anyone's view. They aren't screaming fanatics despite some trying to say that. If they were, they would've been charged as opposed to the Met having to do a huge climb down and send the Chief Inspector plus two high ranking officers to the home of the CEO of Republic to apologise.
They aren't fucking off any time soon, sorry to disappoint.
