A few demonstrators were observed tampering with the gate prior to its opening. Police estimate 10 to 20 protesters entered and began moving down the ramp in the direction of the jail entrance and the building's critical infrastructure. They also placed large tree branches to prevent the gate from closing.
Deputies met the trespassers on the ramp to prevent entry and began ordering them to exit. The crowd, which was described by police as hostile, tossed urine, alcoholic beverages, water bottles and batteries at deputies. Because a large group of people were engaging in angry 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 and directed the Portland Police Bureau incident command to communicate the riot declaration and force warnings to the demonstrators using the mobile Sound Truck. Police issued the declarations and force warnings several times.
Even as deputies instructed people to leave, some of the demonstrators continued to throw projectiles and were basicaLly hostile. The demonstrators then stood at the garage exit, repeatedly preventing the gate from closing by pushing on it.
Again, deputies asked the crowd to step away. Demonstrators ignored the repeated requests and continued blocking the gate. Deputies swiftly moved toward the demonstrators that were preventing the gate from closing to allow space for the gate to close properly. Deputies retreated inside and eventually were able to re-secure the gate. No arrests were made.
