ATLANTA - A Fulton County jury has acquitted a suspended Atlanta police officer charged with shooting an unarmed man.

The jury on Thursday cleared Officer Reginald Fisher of all charges, including aggravated assault, aggravated battery and violation of oath of office, for the May 2009 shooting of Tramaine Miller at an apartment building.

Authorities said Fisher was working an unauthorized off-duty security job when he got into an argument with Miller over illegal parking. Fisher told authorities he thought Miller was reaching for a gun and shot him in the lower left jaw.

Miller told authorities he thought Fisher was a drug dealer. The victim was at the apartments to give medication to his quadriplegic aunt.

The 42-year-old Fisher had been a police officer for a year at the time of the shooting.
