Police war on photography: NYPD disables security cam, then uses 'Stop resisting!' ruse during beatdown

Where there might be witnesses to a beating, some cops will yell "Stop resisting," during the beating so if they are taken to court and witnesses are asked if the police told the victim to stop resisting, said bystanders will have to (if they are truthful) answer yes, thereby corroborating and legitimizing the trick.
     This appears to have happened in New York City recently, where a Crown Heights man intends to sue the city after a group of cops allegedly beat him up at home while shouting anti-gay epithets.

Jabbar Campbell, a 32-year-old forensic specialist, was hosting a gay pride party at his Sterling Place apartment Saturday night when police came to his residence because of a noise complaint. Those officers left after telling the revelers to keep it down, but soon another group of officers returned—and Campbell says one of them disabled a surveillance camera in the building before they beat him up.
     Campbell's eight-room apartment occupies the entire second floor (there is currently no tenant on the first floor). A surveillance camera is installed in the vestibule, and Campbell has shared footage with the media that appears to show an officer reaching up to the camera and tampering with it. “They were trying to open the door, but it was locked,” Campbell tells the Daily News. “They were banging with their flashlights.
     Shortly before 3 a.m. Campbell opened the door for the second group of officers. “There was a sergeant, he yelled ‘get him!’ and that’s when I got attacked," Campbell tells the Post. "They kept saying, ‘stop resisting’ but I wasn’t resisting. I didn’t have any time to respond. One particular officer had a gloved fist and was hitting me in the face." In his interview with the News, Campbell recalls, "They were screaming and cursing saying things like ‘fag,’ ‘homo,’ ‘a--hole,’ just a bunch of anti-gay slurs."
