Furthermore, I think a plausible argument can be made that restricting access to guns in general (especially handguns, assault rifles, and other non-hunting guns) will, over time, result in a cultural shift away from guns. We're talking a cultural change, so I'm aware that's a hard thing to predict, but I think it's certainly a possibility.
edit: was just about to edit into my post when I realized that I had actually posted it correctly.
Isn't that good enough? Instead of worrying about your new loopholes, let's make it harder to kill a lot of people quickly.
"Twenty-two children injured. Versus, at current count, 18 little children and nine other people shot dead. That's the difference between a knife and a gun."
