The Los Angeles trial of a transit officer accused of killing an unarmed man has taken a technical turn, with weapons experts testifying about proper techniques for handling guns.
An attorney for ex-Bay Area Rapid Transit police officer Johannes Mehserle says his client meant to pull out his stun gun instead of his handgun before he shot and killed Oscar Grant on New Year's Day 2009 in Oakland. Mehserle has pleaded not guilty to murder.
During trial Tuesday, a BART rangemaster showed the jury the steps Mehserle would have to take to pull his gun from his holster.
When shown footage of the shooting, another rangemaster, this one from a Napa police academy, said Mehserle didn't appear to follow proper training techniques in the shooting.
