A federal officer holds a tear gas rifle during a Black Lives Matter protest at the Mark O. Hatfield U.S. Courthouse early Sunday, July 26, 2020, in Portland, Ore. On the streets of Portland, a strange armed conflict unfolds night after night. It is raw, frightening and painful on both sides of an iron fence separating the protesters on the outside and federal agents guarding a courthouse inside. This weekend, journalists for The Associated Press spent the weekend both outside, with the protesters, and inside the courthouse, with the federal agents, documenting the fight that has become an unlikely centerpiece of the protest movement gripping America.
