On the night of June 4, New York Police Department officers in riot gear surrounded a group of peaceful protesters in the Bronx shortly before the start of a citywide curfew imposed by Mayor Bill de Blasio and, as the clock struck eight, unleashed a barrage of batons and pepper spray. Protesters were trapped in a mass of bodies by advancing officers and arrested, some clubbed and tackled to the ground for the crime of assembling outside past the curfew. In a week marked by violent outbursts by the police in the face of largely peaceful protests, the incident stood out as uncommonly vicious.
