CLEVELAND (AP) — A prosecutor has told the NAACP in Cleveland that the law doesn’t allow him to release transcripts from the grand jury that voted to not indict two white police officers in the fatal shooting of Tamir Rice, a 12-year-old black boy playing with a pellet gun.

The letter by Cuyahoga (ky-uh-HOH’-guh) County Prosecutor Tim McGinty to the civil rights group was released Wednesday night. In it, he said his office will provide reports anddocuments about lethal uses of force by police but by law cannot release the grand jury transcripts. A grand jury voted last week to not indict the officers in the November 2014 shooting outside a recreation center.

NAACP officials have said they will go to court to seek release of the transcripts if McGinty refused.
