When you're built like a walking tank, you don't necessarily have to be accurate with your gun, but it helps! The interesting thing about Robocop's astonishing marksmanship (at one point shooting a rapist in the junk through his victim's skirt without harming her) is that it's all programming - Officer Alex Murphy was a notoriously lousy shot. When his targeting systems go down, Robo's a klutz with his handcannon. But couldn't you say that about any of us cyborgs?
