Am I the only one who thought of this?

A couple times in today's episode they mentioned "someone is coming at you with a knife, you have a gun. you kill that person to save your own life". Am I the only person who thought "okay well they have a knife...I'd have a gun, right? So why not shoot them in the hand or shoulder or some other non-lethal location to stop them without killing them?" Am I the only one here who thought immediately about the fact that situation could be resolved non-lethally?
