Quentin Tarantino Fires Up Rally Against Police Brutality

Quentin Tarantino took the mic and fueled outraged protesters in NYC who were rallying against deadly acts of alleged police brutality.

Tarantino was right in the middle of a march in Washington Square Park on Saturday ... and eventually stood at the podium in front of crowd and yelled, “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.”

There were tense moments with NYPD officers ... and 11 protesters were eventually arrested for disorderly conduct. The rally came just four days after an NYPD was killed in the line of duty.

Tarantino addressed that shooting, telling the NY Post ... "It's unfortunate timing, but we've flown in all these families to go and tell their stories. That cop that was killed ... that's a tragedy too."
