I'm pretty sure I recall seeing this on the front page of CNN last year, so I'm also pretty sure the whole "the MSM sweeps murders committed by black people under the rug" narrative is false. Furthermore, as others have remarked, a man was murdered, the police investigated and found the likely perpetrators, arrested and incarcerated them, the grand jury in the case issued indictments, and presumably they will stand trial for murder.

There were roughly 47 murders every day in 2019 in the U.S.--murders that are simply "A murders B, A is arrested, jailed, and charged" aren't newsworthy on a national level. Murders that are "A and B murder C, prosecutor refuses to indict, second prosecutor refuses to indict, and only after the video goes public does a third prosecutor send it to a grand jury" are irregular as murders go, and merit national attention.
