When Mrs WBill and I started dating, she was very much in this camp. She'd also not fired anything more powerful than a rubberband across 3rd Period Studyhall.
So, we had a "shooting date" at the local range. First thing that she said was "Wow! This is hard!" and I've not heard her make the 'shoot to wound' comment, since.
So, IMHO, if you hear a comment like "Just shoot the bad guy in the leg", it tells you how experienced the person is that you're dealing with.
And, for what its worth, she went through a basic shooting program put on by the Pink Pistols. She thought it was worthiwhile. I thought so too, in that she'd listen to them (and not to me.....)
