These guys only got a 50% hit rate. Loughner, a kid, with no training that only owned a gun for a little over a month, did better than these professionals.Five of the seven officers investigating the club were involved in the shooting. Detective Paul Headley fired one round, Officer Michael Carey fired three, Officer Marc Cooper fired four, Officer Gescard Isnora fired eleven, and veteran officer Michael Oliver emptied two full magazines, firing 31 shots from a 9mm handgun and pausing to reload at least once.
An autopsy showed Bell was struck four times in the neck and torso. Guzman (31 y.o.) was shot 19 times and Benefield (23 y.o.), who was in the back seat, was hit three times.
