WASHINGTON (AP) — Massive protests against police brutality nationwide capped a week that began in chaos but ended with largely peaceful expressions that organizers hope will sustain their movement. Saturday’s marches featured few reports of problems in scenes that were more often festive than tense. Authorities were not quick to release crowd size estimates, but it was clear tens of thousands of people — and perhaps hundreds of thousands — turned out nationally. Wearing masks and urging fundamental change, protesters gathered in dozens of places from coast to coast while mourners in North Carolina waited for hours to glimpse the golden coffin carrying the body of native son George Floyd, the black man whose death at the hands of Minneapolis police has galvanized the expanding movement. Collectively, it was perhaps the largest one-day mobilization since Floyd died May 25 and came as many cities lifted curfews imposed following initial spasms of arson, assaults and smash-and-grab raids on businesses. Authorities have softened restrictions as the number of arrests plummeted. Demonstrations also reached four other continents, ending in clashes in London and Marseille, France. In the U.S., Seattle police used flash bang devices and pepper spray to disperse protesters hurling rocks, bottles and what authorities said were “improvised explosives” that had injured officers, just a day after city leaders temporarily banned one kind of tear gas. Around midnight in Portland, a firework was thrown over the fence at the Justice Center, injuring a Multnomah County deputy, Portland police Lt. Tina Jones said. Smith said police had declare an unlawful assembly and were making arrests.
