ATLANTA -- A judge ruled on Wednesday that Atlanta's citizens review board can keep the internal police records on the 2006 killing of Kathryn Johnston.

The police union wanted the board to give the records back, saying it's too early to release the documents because of the ongoing investigation.

"Right now they have partial investigations, which is like having the first five chapters of a 10 chapter book. Sure, you can kind of see where the story's going, but you have no idea what the end is," said David Beall, the police union's attorney

But Judge Wendy Shoob ruled against him, saying the impartial citizens review board can begin its own investigation of the two shootings.

The Atlanta City Council issued a subpoena last month, ordering the police department to give records to the Atlanta Citizen Review Board concerning the Johnston case and the December 2008 fatal police shooting of robbery suspect Pierre George.

Prosecutors said they are still investigating the George shooting. The police department is still conducting an internal investigation into the Johnston killing.

Johnston was shot and killed during a botched drug raid at her Neal Street home. Three Atlanta police officers were later sentenced to prison.

Several vocal supporters of the review board attended the hearing, including state Senator Vincent Fort and former Atlanta city Councilman Derrick Boazman.

They believe that even though three officers were convicted in the Johnston case, there's more corruption within the Atlanta police department to be uncovered.

"The citizens can't depend on the Atlanta Police Department to police itself," Boazman said.

"Crime is a problem. But if we're going to face that issue of crime, the citizens have to trust the police department serves them," Fort said.
