Experts say witnesses' testimony bolster the cop's defense

LOS ANGELES — Almost every witness who either recorded video of or saw former BART police Officer Johannes Mehserle fatally shooting Oscar Grant III in the back testified last week that Mehserle looked surprised after he pulled the trigger of his gun.
Most of the witnesses said Mehserle immediately re-holstered the gun after firing, put his hands to his head and looked "shocked," "dumbfounded" and "stunned."
