OAKLAND — A group of about 20 people gathered inside the Rene C. Davidson Courthouse Tuesday to call for the district attorney to press charges against a BART officer who fatally shot a man.

The group, including the mother of Sahleem Tindle gathered with a sign directed at Alameda County District Attorney Nancy O’Malley, chanted and made speeches at the courthouse. Tindle, 28, was killed at 4:41 p.m. Jan. 3 on the 1400 block of Seventh Street across from the West Oakland BART station.

On Tuesday, protesters first went to the district attorney’s office on the ninth floor of the courthouse, and continued their rally in the lobby of the courthouse on the first floor.

“Life taken so tragically, where’s the police accountability?” chanted the protesters as their words echoed in the halls of the courthouse, along with the drums some played.

Last month, after video footage from the BART officer Joseph Mateu body camera leaked and became public, BART police decided to release the full video.

The video do not clearly show Tindle holding a gun, as BART police have insisted, although police cautioned it’s just one piece of information that should not be taken out of context.

Tindle’s mother, Yolanda Banks Reed, spoke during the rally and broke down crying when she spoke of the video. She said she has to look at the video every day, and see her son get shot in the back three times.

“You cannot fool reality,” she said.

Those gathered held a banner that read:

The “District Attorney Nancy O’Malley: Your responsibility is to charge and prosecute any person, whether they be a Civilian or Police Officers under the seal of the law. They must be held accountable for their actions and their offenses.”

Mateu reportedly returned to duty two weeks after the shooting, according to BART police.

Tindle’s family, and attorney John Burris, have maintained that the video does not support the police narrative of what occurred that day.

They said the body-camera footage shows Tindle unarmed and appears to be complying with the officer. Tindle had his back to Mateu and was bringing up his empty hands into the air when he was shot, according to Burris.

Burris has said that the officer didn’t have enough information to justify using deadly force. The family announced potential legal action against BART and the officer.

This is the latest rally that the family and supporters have held, calling for charges from prosecutors. They’ve also gathered at West Oakland BART station last month, and at the BART board meeting this month.
