The people saying that undercover cops are setting fires are drastically underestimating how much human beings love to set shit on fire when they're pissed. It is deeply annoying to be supportive of prosecuting the cop who killed Floyd but seeing all these likewise younger people pulling out literal two year old logic-- you kill one of ours we burn down all of your shit.
"B-but muh American revolution--" That was an organized effort by a militia, not thousands of wild idiots swarming over Target like locusts. This is not going to spark a revolution; the government and media will point only to the violence and looting and say 'these people cannot be reasoned with, look at what they're doing' while disregarding the peaceful protestors.
... Then again, looking at Ferguson which wasn't nearly as bad maybe peaceful protesting doesn't work in this day and age either.
