Anti-police liberals in San Francisco took a victory lap on Tuesday after District Attorney candidate Chesa Boudin declared victory.

At Boudin’s election party, Supervisor Sandra Lee Fewer led a “F*ck the POA” chant, referring to the Police Officers Association.

Watch:

“I just have one thing to say,” Fewer told the crowd, “F*ck the POA!”

The union had opposed Boudin’s candidacy.

The POA sent Fewer a strongly worded letter, demanding an apology.

“Last night, your unhinged attack on the 2,000 San Francisco police officers who make up the San Francisco Police Officers Association (SFPOA) was repugnant,” writes union president Tony Montoya.

He encouraged Fewer to “attend a 40-hour implicit bias training to better understand your apparent hatred of police officers.

“Getting in touch with your feelings about why you hold such disdain for the men and women in uniform working to keep San Franciscans safe is the first step toward healing the pain you have caused.”
