Roughly four hundred protesters faced off with the Portland Police Bureau in a tear gas and firework filled encounter at a Fourth of July protest in downtown Portland, Oregon. Protesters started the night in Chapman Square directly across the street from the Multnomah County Justice Center for a demonstration marked by flag burning, chanting and firework lighting. The protest escalated as the night went on, however, and Portland police eventually declared a riot and used tear gas along with other crowd control munitions to disperse protesters as they launched fireworks at the Justice Center building. Protesters threw fireworks at police as they were forced to retreat toward the Willamette River to escape an advancing wall of officers and tear gas. Police fired roughly 25 cans of tears gas by midnight. Photo by Austin Johnson.
