What nobody is asking for is to ban mentally damaged people (from little monsters in middle school to toothless hobos on the streets) who barely blocked by chemical doses from going murderous/suicidal. There are millions of mentally damaged people who can snap and kill a lot of people.

And this is not mutually exclusive to restrict gun access to users of psychotropic medication.
