I think that schizophrenics, once diagnosed should have some kind of legal oversight, like a probation officer that they must report to or will be in violation of the law. The patient overseer would do a brief evaluation and give the patient their shot (it’s only a once a month shot, not daily pills anymore.
I think that every time a psychologist or psychiatrist makes a diagnosis of serious mental instability, the analyst should become automatically responsible to refer the patient for oversight.
Sedatives work best since they help them relax about all the horrible things they see happening ~ only in their minds. The current idea is they are mostly acting out in a rational way against their hallucinatory voices and images, much as anyone else would.
Once the gene tests are in place we can quickly differentiate between the schizos and the brain damaged folks ~ for whatever good that will do.
