Credit the NYPD for this year’s murder-free J’Ouvert — even if the street party that precedes the West Indian Day Parade wasn’t entirely peaceful.

Cops and city officials this year moved J’Ouvert’s start time from 2 a.m. to 6 a.m. while fencing off the festivities, adding police checkpoints and screening revelers for weapons and booze.

Yet the event’s periphery still saw scattered bloodshed: two men wounded by gunfire around 5 a.m., two others stabbed later on. (The only gun death near the festival area, of a 49-year-old father of two, came nine hours before the 6 a.m. party started.)

The 2015 fatal shooting of Carey Gabey, an aide to Gov. Cuomo, prompted the city’s first effort at a crackdown last year, adding more cops and spotlights, while for the first time requiring organizers to get a permit for the middle-of-the-night pre-party, the only one of its kind in the city.

But the 2016 J’Ouvert still had two revelers gunned down at the festival and several others wounded. That prompted the NYPD to finally nix the pre-dawn action.

It’s likely that “precision policing,” the department’s ever-greater focus on gangs and other known threats to public safety, also helped prevent the worst violence this year.

Some complained that the party’s not as much fun without the old anarchy, and that may be so. But “fun with guns” isn’t a New York value.

All the officers who made the difference this year deserve the praise, support and thanks of the Caribbean-American community and of the entire city.
