Following the not guilty verdict in the high-profile Kyle Rittenhouse case, a riot was declared Friday night in downtown Portland, Oregon, when an Antifa group began to breach the gate into the Multnomah County Detention Center. 18-year-old Kyle Rittenhouse was acquitted on all charges Friday, found by the jury to have acted in self-defense when he shot three Black Lives Matter protests, killing two and injuring the third, during the August 2020 riots that erupted in Kenosha, Wisconsin, over the police shooting of Jacob Blake. Portland law enforcement declared a riot Friday night after BLM-Antifa activists took the streets across majority US cities in solidarity with Kenosha. Rioted and damaged property in downtown Portland as vengeance for the jury's verdict.

Several members of the crowd screamed out "burn it down," referring to the Justice Center, which houses inmates, the central police station, and the sheriff's office. "Because a large group of people were engaging in tumultuous and violent conduct, and further entry into the building would have posed significant implications and grave risk of causing public alarm, the Multnomah County Sheriff's Office declared a riot," the office said in a statement Saturday. FOX 12 Oregon reported the rioters smashed windows and broke doors.

The rioters shattered the rear hatch window of a patrol sergeant's cruiser, windows from the city print shop, and tagged the justice center building, police reported. "All cops are Kyles" was spray-painted across the PPB's central precinct. Antifa rioters blockaded the road outside the Justice Center and chanted, "Kyle is a terrorist!" Attempting to incite violence, the anti-Rittenhouse mob yelled, "Every city, every town, burn the precinct to the ground!"

A dispersal order was issued via social media and loud speakers, instructing rioters to travel west and warning that failure to adhere may result in citations, arrests, and use-of-force, including pepper spray and impact weapons.

You f*cking cowards!" Significant resources were diverted to address Friday's riot, affecting response times. "While we have officers assigned to address emergencies citywide, lower priority calls will have to wait for a while," Portland Police tweeted. White House press secretary Jen Psaki said that the Biden administration has been in communication with law enforcement channels to ensure that whatever BLM protests occur following the Kyle Rittenhouse verdict remain "peaceful."
