If we can admit it, back in 1992 with the Rodney King Simi valley riots in LA, there was a point, one specific point, Red Baron, Mzkitty when the LAPD marched into one intersection, SWAT M-16's waving, looking and acting in full Darth Vader mode, took a look around that one intersection, got a radio call from Darth Vader command, about the 75 OTHER intersections now dissolving into chaos, figured out they could control maybe three of them, and then just turned around and left. You can see on the video where the black people had a light go on realized they were in control, and five minutes later LA was in total chaos.
I'm thinking that moment just happened and there will be no stopping the rioters now, at least not tonight.
