J’Ouvert is Brooklyn’s version of “The Purge” — and needs to be shut down, says a former Bloods gangbanger who turned his life around with the help of slain St. John’s student Tiarah Poyau.

“That J’Ouvert s–t’s got to stop,” fumed Tattuu Phillips, a longtime friend of Poyau and former member of the city’s infamous Valentine Bloods set.

“J’Ouvert has become the Brooklyn annual Purge,” he said, referencing the dystopian horror flick, which centers around an annual 12-hour period when all criminal activity, including murder, is legal.

“If even one person is killed every year at J’Ouvert that s–t has to stop. It has to stop. When did it become cool to focus on the party over life?”

Phillips, who was incarcerated from 1995 to 2002 on drug charges, has been in and out of jail due to parole violations. After his most recent — and last — release in 2012, Poyau became a supportive voice in his life and helped him kick his bad habits.

Phillips said the pair had spent years trying to keep each other out of trouble — and Poyau had even promised to stay away from the pre-dawn debauchery of J’Ouvert.

“She said she’d never go,” Phillips recalled. “Flatbush minus J’Ouvert is a gang melting pot. This area is a problem all year long … When you have that kind of ingredient inside an environment that is already naturally aggressive, it’s a recipe for what happened to Tiarah.”

Phillips recounted how he used to live on Franklin Parkway and Eastern Parkway, and would witness the craziness firsthand.

“I remember in 1994 the first murder that happened on Labor Day on a side block. Dudes were so focused on not getting the party stopped by police,” he said. “A guy got stabbed. When he died, his body started swelling, [and] instead of calling the police, they dragged his ass to the side of the building. I remember watching grown men, I was about 15 years old, take a cardboard box and lay it over him just so the parade could continue. They said, ‘If we call the police, they’ll stop the partying. He’s already dead. We can’t save him.'”

While J’Ouvert is meant to be a celebration of Caribbean culture, Phillips said it is nothing but an excuse to get wasted.

“Next thing you know, you get drunk and you want to get violent — that’s where it comes from,” he said.

Phillips believes Mayor Bill de Blasio should just “dead” J’Ouvert — meaning shut it down.

“I say forget all of the money. Forget all the taxpaying money that’s going into security, that’s going into extra police, so the police can function. Just dead that s–t,” he seethed. “Use that money that you would normally use to help police J’Ouvert and bring it up to the parade. Let the parade use that extra security. To help deter people from getting their purge on.”

Since his release, Phillips has gone back and gotten his GED and has been actively involved in a local church helping young people stay away from gangs. He said the last time he spoke to Poyau, she was on vacation in Japan.

“Tiarah just returned from visiting her dad,” he said. “She was like, ‘You got to keep moving around, Tattuu. I’m telling you, surround yourself with good people.'”

Phillips said one of the biggest reasons the mayor should cancel J’Ouvert is to keep people from setting a bad example for the city’s kids.

“You guys are not going to run this into the ground and make this an every year thing where it’s, ‘Oops, our bad,'” Phillips said. “If you dead J’Ouvert, that’s 250,000 people that are not in the streets … The parade is enough. Come out, wear your flag, represent your culture, eat good food, listen to good music and then take your ass home.”

The ex-con also insisted the hecticness of the festival — which takes place before the West Indian Day Parade — is another reason why de Blasio should put an end to J’Ouvert.

“The ‘purgers’ are out throwing powder in the air. You can barely see. The barricades become death traps because there are so many people crammed into those little areas that as soon as something happens, it’s like sardines trying to get out of a little can,” he explained.

In the end, Phillips ultimately thinks that keeping the festival alive and running will only lead to more bloodshed.

“I just feel that every death that goes down at J’Ouvert reinforces for the next year of purgers that ‘Yeah, you can get away, you can commit murder in the midst of all of those police,'” he said. “It’s like a challenge to these guys now. They’re like, ‘Oh, let’s see if we can really kill somebody. Let’s see if we can take somebody’s life with police being right there.’ That’s what these guys are doing … I don’t even know certified gangsters that were shooting people that much.”

Poyau, who was at the event with friends, was fatally shot in the eye early Monday just moments after she told a drunken reveler who was trying to grind up on her to “get off me.”

On Wednesday, police officials said that Reginald Moise, the 20-year-old thug accused of shooting Poyau with a Glock 9mm, is not the same person who tried to dance on her.

Moise was arraigned on a murder charge in Brooklyn Criminal Court Wednesday night.

“[A witness] described the male that was bothering [Poyau] as a heavyset male,” Boyce said at a press conference. “Mr. Moise is razor-thin. So we don’t believe that’s the case, that he’s the one who attempted to grind her from behind.”

Authorities are still investigating the fatal shooting of 17-year-old Tyreke Borel, who was also killed during the festival. Officials said the incident was unrelated.

“What the hell is a 17-year-old kid doing out at 4 in the morning!?” Phillips asked. “There are people outside, 13 and 14 years old and younger. Why? Because every year it starts to get accepted by the younger generation. It has to stop.”
