Police Use Force Against Protesters at NYC Queer Liberation March | NowThis
They were met with a violent response by some NYPD members. The march began in lower Manhattan, went around the Stonewall Inn, and ended in a rally at Washington Square Park. In one altercation, a police officer charged at protesters, yelling, ‘Get off the street.’ The NYPD said it arrested at least 3 people at the march but it was unable to give a full count. Protesters intervened as police were arresting 2 people for graffiti, and the police responded using pepper spray, according to witnesses who spoke to Gothamist. The march was held on the 51st anniversary of the 1969 Stonewall uprising.
