The standard thing that leftish progressive anti imperialists will say, and this is BC it's one I've heard a Lot, is the a riot is the voice of the unheard.
Obviously this didn't apply to the riots in 2024 after the Southport murders. That was different.
It's also why when the right started using the playbook of the left, ie the "2 tier Kier" jibe to suggest policing was unfavorable to those in the non ethnic minority population, it was particularly triggering for a lot of people to see their policy positions retooled and used against them.
