At least 75 protesters marched toward the Portland Police Association (PPA) office on Monday night with “support vehicles” in tow, before setting fire to a nearby billboard, according to authorities.
When they arrived, at around 10:20 p.m., police warned those in the area over a loudspeaker to remain on the sidewalk, and “be courteous to your neighbors” because the nearby streets around the police union building were open to vehicular traffic.
