Atlanta police chief resigns after fatal police shooting

Days later, Shields fired two officers and benched three others caught on video May 30 in a hostile confrontation with two college students whose car was stuck in traffic caused by the protests.

The officers shouted at the pair, fired Tasers at them and dragged them from the vehicle. When prosecutors charged six officers with crimes in the incident, however, Shields openly questioned the timing and appropriateness of the charges.

The shooting of Brooks two weeks later raised further questions about the Atlanta department.

In a statement, Shields said she chose to resign "out of a deep and abiding love for this city and this department." "It is time for the city to move forward and build trust between law enforcement and the communities they serve," Shields said.

Reynolds said his agents worked through the night interviewing witnesses and reviewing video. He said their findings show that Brooks tried to fight off two officers when they tried to arrest him and at one point managed to take a Taser away from one of them.

A security camera recorded Brooks "running or fleeing from Atlanta police officers," Reynolds said. "It appears that he has in his hand a Taser." During a short foot chase Brooks "turns around and it appears at that time he points a Taser at an Atlanta officer," Reynolds said. That's when the officer drew his gun and shot Brooks, he said, estimating the officer fired three times.

Reynolds said his agents will turn over results of their investigation to Fulton County District Attorney Paul Howard, whose office will decide whether criminal charges are warranted against either of the officers.

Howard said Saturday his office "has already launched an intense, independent investigation of the incident" without waiting for the GBI's results.

The officers involved in the shooting were not identified.

Brooks died after being taken to an Atlanta hospital. One of the officers was treated and released for unspecified injuries.
