(Portland, OR) -- The 70th consecutive day of protests against police brutality and systemic racism in Portland ended with police declaring a riot for the second night in a row. The Oregonian reports more than 200 protesters were gathered at the Portland Police East Precinct last night when a handful of people started removing plywood from the building and trying to form barricades with dumpsters. Police declared a riot just before 10 p.m. and set off stun grenades as they pushed protesters out of the area. Officers detained four people. A smaller and calmer protest in the downtown area ended with demonstrators showing Black-made films.
