An NYPD captain pleaded guilty before the Civilian Complaint Review Board on Thursday to pointing his gun at two innocent boys as they were playing tag on their Brooklyn block in 2013.

Capt. Brian McCaughey admitted to charges of improper force, abuse of authority, and discourtesy, and will be docked 30 vacation days.

McCaughey was a lieutenant with Bedford-Stuyvesant’s 79th Precinct on Sept. 13, 2013, when he pulled his service weapon on 12-year-old Jahniel Hinds and 13-year-old Kasean Smalls on the Quincy Street block where they lived.

The lieutenant and a number of his officers were responding to a call of a fellow cop in need of back-up on a nearby street around 7:40 p.m. when they spotted Smalls and Hinds running down the block as part of a friendly game of tag.

“Get on the ground, motherf—er,” McCaughey reportedly screamed, gun drawn, at the then 5-foot-6, 96-pound Smalls as the 4-foot-9, 88-pound Hinds ran for safety.

“I got on the ground. I didn’t resist or anything,” Smalls, now 15, recalled after McCaughey entered the plea at One Police Plaza. “I was nervous. I was just hoping that anything didn’t go bad.”

Smalls was handcuffed and briefly detained as cops sorted out the confusion with the boys’ guardians.

“[My grandmother] was very mad and angry, but I just told her that I was OK because I thought it would calm her down,” said Smalls.

“I was just hoping that they didn’t pull the trigger,” said grandmother Yvonne Smalls. “I didn’t even have to ask what did he do, because Kesean has always been a non-confrontational kid. It was more of a matter of why [the police were] doing this.”

Hinds, now 14, said he’s been afraid to play outside since the run-in.

“It was mad scary, and I didn’t really want to play outside like that no more. I just don’t run around outside,” he said. “I think [police] should be more careful what they do, instead of just jumping right out on kids playing in the street.”

Hinds’ mother, Corinia Sivers, commended McCaughey for admitting guilt and accepting his punishment, but said she’d wished more of the officers there that day had come forward.

“He was the only one that stood up and took the blame. More of them should’ve been here. I do commend him on that part,” Sivers said.

The 39-year-old mom added that the incident changed the way she tells her son to act around cops.

“I always tell him, don’t put the hood on your head, don’t be running,” Sivers said. “I sit and I talk with him, because all officers are not bad. It’s very few that make it worse for the rest of them.”
