Big Sean has a message for Nipsey Hussle’s killer.

Nearly two months after the Crenshaw rapper was gunned down outside his Marathon Clothing store, the Detroit rapper is sharing his thoughts on the senseless murder of his friend. In an Instagram video, Sean reflected on the day Nipsey was killed and how his death could have been avoided through communication.

“It’s something that’s been on my mind really since Nipsey’s funeral, well, actually since he died,” he began.

He then addressed Eric Holder, the man who allegedly shot and killed Nipsey. “To the person who murdered Nipsey, to people like that who take somebody’s life out of impulse or for revenge or whatever the case may be, you’re making a permanent solution to a temporary problem. Obviously, that’s not how you solve them problems.”

He continued, “I don’t know if we know the value of a life for real ’cause when you take somebody’s life, you send back they family, you send a whole lineage back, generations […] When you take somebody’s life, you setting all that back and for what? For something that could have been communicated better.”

He admitted that he himself is a work in progress. “I myself am a terrible communicator. I’ve been working on it,” said the 31-year-old MC. “I’m becoming better. It takes a lot of effort. I have noticed in men, and in black men, we talk to communicate certain ways. We talk to be tough, we talk to stand tough. Get your revenge, retaliate through violence, all that type of shit. But we gon’ keep losing kings—we gon’ keep losing Martin Luther Kings, we gon’ keep losing Malcolm Xs, we gon’ keep losing Nipsey Hussles—and for what?”

During his PSA, he also offered a solution. “I think if we just put our egos aside, put our pride aside, talk things out, who knows, maybe we’ll still have a lot of them people. Maybe we still have Nipsey, maybe we still have a lot of the soldiers we lost.”

In closing, Sean shared some advice from his mother. “My mom always used to say and people always used to say, ‘Communication can save a nation,'” he said. “It didn’t mean shit to me, but now it definitely has a whole new meaning. Facts.”

Over the weekend, Sean paid tribute to Nipsey during DJ Khaled’s performance on the season finale of “SNL” with Meek Mill, Lil Wayne, SZA, John Legend, and more.

In April, Holder was arrested and charged with one count of murder, two counts of attempted murder, and one count of possession of a firearm by a felon after fatally shooting Nipsey and injuring two others. If convicted of murder, he faces between 25 years to life in prison.
