The Fraternal Order of Police, which counts more than 300,000 police officers among its ranks, has a “surprise” in store for Quentin Tarantino and his film, The Hateful Eight.

“Something is in the works, but the element of surprise is the most important element,” Jim Pasco, executive director of the Fraternal Order of Police, told The Hollywood Reporter. “Something could happen anytime between now and [the debut of Hateful Eight]. And a lot of it is going to be driven by Tarantino, who is nothing if not predictable.” Pasco added that his group, the largest police organization in the world, would be “opportunistic.”

Tarantino has come under attack from police groups ever since participating in a rally against police brutality. “I’m a human being with a conscience. And when I see murder I cannot stand by,” Tarantino said last month. “And I have to call the murdered the murdered and I have to call the murderers the murderers.”

Those comments drew the ire of many, including NYC Patrolmen’s Benevolent Association president Patrick J. Lynch, who called Tarantino a “cop-hater.” Police organizations around the country called for a boycott of The Hateful Eight, which is out on Christmas Day.

“That’s their way. They’re being inflammatory, they’re slandering me,” Tarantino said of the controversy in an interview this week. “I’m not a cop-hater, but that’s the way the attack me is calling me a cop-hater. … It’s much easier to feign outrage and start arguments with celebrities than to deal with the fact that the citizenry has lost trust in them.”

Tarantino has received some support since making his comments, including from director Michael Moore, who wrote on Instagram that certain police officers are “out to get Tarantino.” And in speaking to THR, Pasco said some kind of retribution was part of the agenda.
