A group of activists crashed the wedding of a Sacramento cop who fatally gunned down an unarmed black man in March.

Stephon Clark, 22, was shot eight times March 18 — seven times in the back — while standing in the back yard of his grandmother’s home, by two police officers investigating a report of a man breaking windows.

Though the police department hasn’t released the names of the officers involved, citing security concerns, their identities were revealed by prominent Oakland civil rights attorney John Burris in March, according to the Sacramento Bee.

On Sunday, one of them appeared to be getting ready for his nuptials with his groomsmen when, according to video posted on Facebook, a small group of Black Lives Matter protesters stormed in, yelling, “Murderer!”

“I wonder how you’ve been sleeping since March 18?” a woman asks. “And I know this is supposed to be the happiest day of your life, he will not have that option.

“I just wanted to know if you started planning your wedding before you killed Stephon Clark or after?” she adds, before being asked to leave and getting ushered out by a member of the wedding party.

The protest group said they planned the confrontation when they found the officer’s wedding website, with information about the venue, a vineyard about an hour outside of Sacramento.

“I think they need to be approached in spaces where they’re a little more vulnerable,” Black Lives Matter founder Tanya Faison told CBS Sacramento. “We’re not violent, we’re not gonna give to them what they brought to our community, we’re not gonna hurt anyone but we are gonna make them uncomfortable. And they should, because someone is dead.”

“Stephon Clark’s family is still in mourning and suffering. He doesn’t get to be with his kids or get married,” Faison said.

The case, which sparked protests across the country, is still under investigation and the district attorney has not said whether the officers will be prosecuted.

The two cops have received a number of death threats since Clark’s shooting and have been sidelined to desk duty, Sacramento police said.

“People may think that these officers are just going about their lives, but this is a very traumatic event for everyone,” said Sgt. Vance Chandler.
