That’s too bad.
But the premise appears to have merit. Over diagnosis and over prescribing of psychiatric meds can lead to violence.
The over-diagnosis alone should give us pause. As we all know, The Soviets used psychological diagnosis to imprison political opponents and suppress any activity against the Sate.
I don't have the figures but say it's 0.01 percent of users are affected thusly. Sounds like a small, acceptable number and therefore, the drugs are released to market.
When the user population becomes large (enormous) that 0.01 % becomes a population and not a point.
