The Los Angeles Police Department union has joined its New York counterpart in boycotting director Quentin Tarantino's films after the director took part in an anti-police protest Saturday, four days after one of New York's Finest was murdered by a suspect he was pursuing.

"We fully support constructive dialogue about how police interact with citizens. But there is no place for inflammatory rhetoric that makes police officers even bigger targets than we already are," Craig Lally, president of the Los Angeles Police Protective League, said in a statement Tuesday.

Tarantino, whose oeuvre includes the notoriously violent films "Reservoir Dogs", "Pulp Fiction", and "Django Unchained", flew in from California to take part in the event with hundreds of other demonstrators.

"Film director Quentin Tarantino took irresponsibility to a new and completely unacceptable level this past weekend by referring to police as murderers during an anti-police march in New York. He made this statement just four days after a New York police officer was gunned down in the line of duty."

Lally continued, "We fully support this boycott of Quentin Tarantino films. Hateful rhetoric dehumanizes police and encourages attacks on us. And questioning everything we do threatens public safety by discouraging officers from putting themselves in positions where their legitimate actions could be falsely portrayed as thuggery."

Tarantino spoke out at the rally in Manhattan's Washington Square Park saying, 'When I see murders, I do not stand by...I have to call a murder a murder, and I have to call the murderers the murderers."

The rally came four days after NYPD Officer Randolph Holder was shot and killed while chasing a gunman in East Harlem. When the "Django Unchained" director was asked about the timing of the protest he said it was "unfortunate" but said the rally had to go ahead because people had traveled long distances to attend.

The Weinstein Company, the studio behind Tarantino's upcoming flick "The Hateful Eight," did not return FOX411's request for comment.
