The alleged presence of rioters in the neighbourhood justifies the police being there in armed convoy through the neighbourhoods. It doesn't justify any of their actions shown in the video, which shows a large section of street with no evidence of rioting and unprovoked fire on people in their gardens to a enthusiastic call to action usually reserved for strikes on military targets.

The area does look remarkably clean to have just had rioters on the street. There’s zero trash or debris on the ground, zero evidence of paint or smoke canister usage anywhere, and all of the houses and cars are immaculate. If there were people on the street prior to these police/soldiers arriving, it’s hard to imagine that they were looting or rioting.

So that makes it a lot better that police made a mistake and did it.....
