I dunno, maybe a checkbox for psychotropic meds. Worth discussing that, methinks. Also reports from doctors who prescribe, and an admonition from the doctor to the patient, “if I prescribe this med, one of the side effects is possible suicidal or homicidal thoughts, so I am obliged to report this prescription to NICS. If you take this prescription, you agree to relinquish your right to keep and bear arms.”
(A certain former occupier of the White House, who is and was doubtless a flourishing garden of STDs was all for medical privacy. I don't know why. He looks like he's lost a LOT of weight, I want to know what diet he's on...)
