Brian Nichols trial
During court proceedings in Brian Nichols' trial, retired Fulton County Deputy Grantley White (right) and prosecutor Clint Rucker demonstrate Monday how Nichols held a gun on White in the 2005 Fulton County Courthouse killings. Nichols is accused of murdering Judge Rowland Barnes and court reporter Julie Ann Brandau at the Fulton County Courthouse before escaping the facility and gunning down Deputy Sheriff Hoyt Teasley and David Wilhelm, an off-duty federal agent.
