Are people with mental problems more likely to go on a rampage if they are under the care of a psychiatrist/psychologist? They need to do a study on that.
There are 317 million people in the US, yet a mere handful distiguish themselves as mass murderers. I could point out a large percentage of inner city yutes have a greater chance of becoming murderers.
That depends on the mental problem.
Are the effects of a toothache like the effects of a stroke?
There is a pretty wide range in mental health issues as to what the effects are, the duration, the cause, and the completeness of recovery.
PTSD (as an example) arises from unprocessed memory of a traumatic experience. Mild cases are completely recoverable, and relapses are unlikely.
Schizophrenia has a stress component and a genetic component. Treatment is often lifelong.
And those.just address completeness of recovery, not potential for violence.
The question as posed is so broad as to have no possible intellectual solution (other than to break it down. )
“Are people with mental problems more likely to go on a rampage if they are under the care of a psychiatrist/psychologist? They need to do a study on that.”
Shrink here: Studies of “the seriously mentally ill” - i.e. Schizophrenia and Bipolar Type I - show that they are no more likely than anyone else to become a danger to others . . . as long as . . . 1. They take their meds as prescribed, 2. They don’t use drugs or alcohol, and 3. They have no past history of violent behavior to others. That sub-set represents perhaps 10% of those living outside institutions . . . . It also cannot be extrapolated to other psych illnesses, such as this young man’s extreme narcissism.
To answer your question: No, I don’t think so. Most professionals do the best they can under the law to keep folks with mental illness from hurting themselves or others, but there’s really little they can do realistically in most cases in most jurisdictions. (The Tarasoff Ruling, BTW, put an unbelievable burden of protection on such professionals, a burden that is unprecedented in any other field, even law enforcement and the judicial system, as can be seen in this case and many others.)
