Portland Police Declare Riot For Second Night In A Row

Protesters in the city have been demonstrating nightly for over two months since George Floyd's death. On a recent Wednesday, they attacked a police precinct, damaging property and starting a fire. Police found a suspected explosive device, which was later determined to be non-explosive, and dispersed the crowd. Protesters are demanding the defunding of the police department and the dropping of charges against arrested demonstrators.
