for assault weapons and hand guns a mental evaluation has done, or multiple choice, something like that.
what are you going to do when you fail that test?
I don't like the mental evaluation solution at all. the guns were likely obtained illegally anyway. I like the idea of increasing security in these "gun-free zones". I can't have a gun to protect my family/self? then you better make damn sure no whack job can get in with a weapon of any sort.
maybe we can check for mental disease somehow in the background check that is done when you buy a gun now? I don't know how we would go about doing that but surely it can be done.
