NYPD cops violently arrest dozens of Martin Luther King Day marchers after state sues them for violence

Half a year after the police murders of George Floyd and Breonna Taylor sparked widespread national protests, little has changed in the behavior of some of the most violent police departments in the country.

That much was made obvious on Monday night when a phalanx of hundreds of NYPD charged a Black Lives Matter Martin Luther King Day protest, violently beating and arresting dozens of protestors. “They weren’t approaching the police in a violent manner. Police randomly surged,” recounted witness Ms. Plaza to the New York Times

US: New York Police Planned Assault on Bronx Protesters

Trapping, Beatings in June Crackdown Reveal Abusive, Unaccountable System


New York City police planned the assault and mass arrests of peaceful protesters in the Mott Haven neighborhood of the South Bronx on June 4, 2020, Human Rights Watch said in a report released today. The crackdown, led by the department’s highest-ranking uniformed officer, was among the most aggressive police responses to protests across the United States following the police killing of George Floyd in Minneapolis, Minnesota, and could cost New York City taxpayers several million dollars in misconduct complaints and lawsuits.

Human Rights Watch and the visual investigations firm SITU Research also released a video using three-dimensional modeling, witness interviews, and footage recorded at the protest.
