Nice idea, John, but most people who hold a FFL are not qualified to assess the mental status of anyone. As someone who works in the mental health field, a mini mental status exam covers a number of areas that would be difficult to assess with a pencil and paper or computer test. To do one competently, I need to see the person and evaluate their manner and content of speech, physical appearance to assess how well they seem to be glued together as well as a host of other things. It takes awhile to do one which would be more time than the average gun seller is going to want to spend. Part of the problem is the difficulty in getting someone hospitalized against his/her will. Holmes should have been involuntarily committed, but was not.
