Quentin Tarantino stepped in it.

The famed director – whose films are notable for which characters are slaughtered in a grotesque fashion – attended an anti-police rally in New York City just days after Officer Randolph Holder was killed in the line of duty.

At the event he unleashed a hate filled rant blasting cops as murderers.

As Foxnews.com reports:

“This is not being dealt with in any way at all. That’s why we are out here. If it was being dealt with, then these murdering cops would be in jail or at least be facing charges.”

“When I see murders, I do not stand by,” Tarantino added. “I have to call a murder a murder, and I have to call the murderers the murderers.”

Tarantino’s father – who grew up in New York – joined the Patrolmen’s Benevolent Association and called out his son’ outlandish rhetoric.

According to Foxnews.com:

“I love my son and have great respect for him as an artist but he is dead wrong in calling police officers, particularly in New York City where I grew up, murderers,” Tony Tarantino said in a statement released on Friday by the Patrolmen’s Benevolent Association Of the City of New York. “He is a passionate man and that comes out in his art but sometimes he lets his passion blind him to the facts and to reality. I believe that is what happened when he joined in those anti-cop protests.

In a Skype interview with FOX411, Tony Tarantino said his son “gets extremely emotional and involved through his passion on what he thinks is right, and in my opinion he went off totally without putting a lot of thought and consideration into what he was doing or saying.”

Being criticized by his own father is not the only public backlash the director is facing.

A police boycott of Tarantino’s new film, The Hateful Eight was organized and as thewrap.com reports:

“The police boycott of Quentin Tarantino‘s “The Hateful Eight” has received the endorsement of the National Association of Police Organizations — a group representing 1,000 police units and associations and over 241,000 sworn law enforcement officers.

Not only does the organization support the protesting unions, including cops in New York, Los Angeles, Houston, New Jersey, Chicago and Philadelphia — they are discouraging police officers from engaging in promotional efforts and any future productions that routinely need their assistance.

“We ask officers to stop working special assignments or off-duty jobs, such as providing security, traffic control or technical advice for any of Tarantino’s projects,” a statement on NAPO’s website said.

This could blow up in Tarantino’s face as the film’s bottom line suffers.

Off duty police officers are used to provide security as event staffing for red carpet premieres and film production.

An organized and wide spread boycott by law enforcement and Americans who understand the difficult job police officers undertake could make promoting the film more difficult, add costs to future productions and damage the movie’s box office appeal.

In Hollywood they like to say there is no such thing as bad publicity. Quentin Tarantino may learn there is an exception to every rule.
