So, after some internet research I have concluded that most states have some sort of limitation on firearm purchases to those classified as having or having had a mental "illness" or "disorder". I have some pyschology schooling and after more research discovered that these classifications are very open to subjectivity. For example "specific phobia" could be a fear of snakes, or flying, or heights. There is "generalized anxiety disorder" which basicly means your an anxious person. My point is that nearly anybody can fall into one of these catagories and therefore (possibly) would be barred from purchasing a firearm. Is it possible that a good citizen would need to lie about a fear of heights to buy a gun? Would this be an easy path the preventing the sale of guns as a whole?
