Just four days after the on-duty murder of a hero NYPD street cop, a rally in Washington Square Park against “police terror” devolved Saturday into a raucous, law-enforcement gripe-fest.

Protesters held signs reading “Rise Up! Stop Police Terror!” and “Murder with a badge is still murder.”

“No racist police!” some among the crowd of 300 protesters for the “Rise Up October” chanted, before the rally spilled out of the park and up Fifth Avenue to Times Square.

The NYPD arrested 11 protesters, charging most of them with disorderly conduct, obstructing vehicular traffic and failing to disperse. At least one was charged with resisting arrest.

Director Quentin Tarantino fired up the crowd by complaining that cops are too often “murderers.”

“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 “Pulp Fiction” auteur blathered to a cheering rally-goers.
