Police officers in New York City, Philadelphia, and Los Angeles are joining together to boycott the films and work of director Quentin Tarantino. The boycott is following comments made by the director at a rally against police brutality.

The New York Times reports that Tarantino was among protesters at a New York City rally Saturday, which called for action to be taken against those killed in police shootings nationwide, this year.

Tarantino flew from California to New York for the rally and said during the event, “I am a human being with a conscience.And if you believe there’s murder going on then you need to rise up and stand up against it. I’m here to say I’m on the side of the murdered.”

Patrick J. Lynch, the president of the New York City Patrolmen’s Benevolent Association referred to Tarantino in a statement as a “cop-hater” and that his work, such as Pulp Fiction and Kill Bill is “glorifying crime and violence.” The rally and Tarantino’s statements followed less than a week after the shooting of a New York City officer.

New York City police commissioner William J. Bratton has said, following the rally that, “There are no words to describe the contempt I have for him and his comments at this particular time.”

The comments were not well received by forces in California, either. Officials there said his words “took irresponsibility to a new and and completely unacceptable level”

RiseUpOctober, the organization that held the rally said that the protest and condemning remarks were efforts to discourage protesters. An organizer for the rally said that they are trying to deliver a message to anyone who speaks out, adding that they are trying to scare people into silence.
