Police have argued that the protesters were part of a “black bloc” conspiracy to destroy property. But neither of the people hit by the grenade were wearing black. The only person in black, to the left of the screen, is wearing a black tracksuit with white stripes and a red hat, looking more like a German tourist than a member of an anarchist conspiracy. It wasn’t a MAGA hat, but it would be hard for a cop to tell from a distance.
