The Portland police bureau came out to the game locked and loaded, full riot gear, trucks modified to hold ten cops hanging on the outside, tear gas, flash bangs, pepper balls, rubber bullets, riot batons, helicopters, spotlights. And, they decide to starts gassing protesters half an hour before curfew begins...
Protests started loud but moderately peaceful; no thrown objects, no fires, no damaged buildings. Cops tear gas and shoot them for "obstructing traffic". After a few hours of this, the crowd starts throwing water bottles, breaking windows, hurling the tear gas grenades back. This back and forth goes on through Sunday night.
Portland mayor Ted Wheeler gets a LOT of flack from important people who spent their weekend coughing on tear gas and waking up to sirens, painful screaming, and flashbangs, instead of drinking fine wine at nice restaurants and walking the Pearl District. He tells the cops no more violent riot control measures.
Monday night hits, something like 10,000 protesters take the streets and bridges, organized, geared up with cones, leaf blowers, shields, gas masks, body armor. The cops stay put. They don't even come out of their staging area. Protesters spend the evening chanting, talking to passersby, and policing bald headed agent provacateurs wearing German camo to hide their swastika tats. It was beautiful, the air was breathable, and there were no reports of looting or damage.
