Of the thousands of protests more than 90% of them had no property damage, no injuries (to police or anyone)reported , and no arrests.
You seem to be claiming that there actually was... but it just happened after the news cameras went home.
If CNN etc went home at 8pm from every peaceful protest.. and if from that point on, all the peaceful protests would devolve into a riot... and then 8am the next day the local Target is a smoldering pile of rubble, 10 people are in jail for beating cops and there are dead bodies in the street, I somehow doubt there would be no record of it.
It would have had to be covered up and physical damage to the city literally cleaned up. I haven't seen any proof of that happening... and no, a lack of evidence is not proof.
"And where was the left? They certainly didn't condemn it. They more than tolerated it. They told the police to stand down and let it all happen"
I condemned violent riots. It was clearly bad for local communities and counterproductive to the movement. (And that's basically what Kamala was saying too. ) I also screenshot footage of the people from the pawnshop robbery where officer David Dorn was murdered and posted it with the local police number to call if you had any information about them.
Anyway the problem is there were so many protests that even if a small % turned violent, it would be a large total number. For example if there were 2,000 peaceful protests and only 5% turned into violent riots, that is still 100 violence riots. (Which would be more than enough riots to cause the destruction described by you... billions of dollars in property damage + 80 deaths)
Also Antifa are basically anarchists and have protested against both Repubs and Biden and the dems.
