Interesting. So you dont think mentally ill people should be under some type of evaluation? You turning this into some type of Constitutional Law situation is laughable. Your line of thinking is the reason there are so many mentally ill people running around on the loose in America and quite frankly, in this forum. Severe mentally ill people (I"m not talking the garden variety Trump level of mental instability although I might even question that) should not be allowed to own guns. Period. If you think mentally ill people SHOULD be allowed to own guns, then you probably need your head checked as well.
Amendments are available as America changes. Our founders were smart enough to realize things change.
