About half the people killed by US police have a mental illness. Police do need to be careful but shooting people is probably not the right thing to do in most of those cases.
Better training in de-escalation and rapid tranquilisation and psychiatric nurse accompaniment would be better.
Your first point needs a citation. If someone has an adderal prescription, would you say they have a mental illness? that is a rather ambiguous description.
They do need to be more careful. So careful that maybe a human is not up to the job...
This report talks about a "serious mental illness".
Those words tend to be used for diagnosed mental illnesses like schizophrenia and other psychotic illnesses, sometimes major depression or severe bipolar disorder. Very roughly one or two people per hundred meet this definition.
An appropriate adderal prescription would be for a mental illness or mental health problem. It would tend not to be described as "severe and enduring". This "severe" label is in the context of mental illness, not the general population; it's not meant to imply that ADHD etc are trivial.
