It seems like smart thinking to me, people were burning down and taking over chunks of cities in the US, personally I don't want that happening in London and if it did would support the, well not very big guns in the grand scheme of things, being brought out. To be fair, I'd support them doing the same to far right protests if the same level of rioting took place.
I'm not asking them to open fire into a peaceful crowd inindiscriminately am I? I'm saying if it kicked off and they started burning buildings and looting like the US BLM riots, then I wouldn't be opposed to the use of the rounds.
the demonstrations in the u.s. were largely peaceful aside from police violence. a ransacked Target is not worth the police running people over or blinding them with rubber bullets
