They are protesting the death of Patrick Kimmons who after shooting two people, was rendered hors de combat by Portland PD. somebody got the rumor started that Mr. Simmons was unarmed and was shot some 700 times in the back so this being Portland, the crazies came out to play.
The lady was not happy about the noise and the Left Wing Birds of Annoyance came to mess with her. Classy!
After that, the usual “F Us” back and forth between other shouting parties, no exchange of violence.
