Appearing on U.S. show Real Time with Bill Maher on Friday (06Nov15), the director discussed the controversy surrounding the comments he made during a rally in New York on 24 October (15).

"I'm a human being with a conscience," Quentin said at the time. "And when I see murder I cannot stand by. And I have to call the murdered the murdered and I have to call the murderers the murderers."

In response to his comments, a spokesman for The Fraternal Order of Police, the largest union for sworn officers in the U.S., said that it had a "surprise" for the director, but would not reveal its plans.

Police across the country have also been urged to boycott his upcoming film, The Hateful Eight, which is due out in December (15).

Quentin told host Bill on Friday that the backlash from law enforcement agencies around the U.S. has started to make him feel uneasy.

"It's interesting," he said. "I'm now all of a sudden looking into my rearview mirror again and I'm seeing the bubblegums - police cars - again in a way that I haven't thought about in 20 years."

The director said he was fine debating with police over what he actually said, but he will not discuss an "interpretation" of what he said.

"If they were saying what I said and they had a problem with that, well then now we're actually talking about the problem," Quentin told Bill. "We actually do need to talk to the cops about this. We actually do need to get to the problem. We need to bring this to the table."

He told the host he will continue talking about the issue of police brutality in the U.S., and said he wants the law enforcement institutions not to close ranks on what he calls "bad cops".

Quentin added, "I actually don't think it is an issue of individuals, good cops verses bad cops. I think it's inside of the institution itself. If they were really, really serious about this, they wouldn't close rank on what I'm obviously talking about, which is bad cops. And I'm obviously talking about specific cases where it is murder as far as I'm concerned."
