“We’re sick and tired of you killing people!” Winston shouted through a megaphone.
Portland Mayor Ted Wheeler, who visited the park, encouraged everyone to protest peacefully.
“These shootings always are traumatic for everyone involved and for our community, regardless of the circumstances,” Wheeler said in a statement. “I recognize why people are concerned and possibly angry. While our understanding of this incident evolves, I urge everyone to proceed with empathy and peace.”
Portland has been the site of some of the most intense demonstrations since last year, especially those focused on police reform after George Floyd, a black man, died in police custody in Minneapolis after an officer knelt on his neck for more than nine minutes.
Far-left protesters have also been critical of Wheeler, who faced mounting pressure to resign over accusations that he didn’t do enough to clamp down on police use of force or stop growing violence. Last year, protesters lobbied the Portland City Council to cut $50 million from its police department, but the council only went as far to strip $16 million.
