Involuntary psychiatry is a violent practice that strips its victims of all human rights and effectively all due process. It is an unimaginable horror that can possibly lead to coercive psychiatry or medicalized rape.
“who appear to be mentally ill and who display an inability to meet basic living needs” could be taken against their will to a hospital for a psychiatric evaluation.
Not being able to provide for your needs is not mental illness. An appearance of mental illness is not proof that somebody needs involuntary commitment. First responders are not equipped to diagnose mental illness - this is a stripping of rights and imprisonment.
If somebody is unable to provide for their needs, give them the ability to do so. Provide food, real housing, actual medical care, and an option for outpatient mental health care for them to recover if they are not in crisis.
I understand some people are severely mentally ill, are in crisis, and are a DANGER to themselves and others and need care ASAP, but this is just targeting impoverished individuals, who may be homeless, based on what is effectively hearsay.
We can do better than this as a society.
Find a way of treating them and helping them to adjust to society without the use of coercion or a violation of their rights. That means giving them real legal representation, giving them access to courts that are open to public observation (mental health courts are NOT sufficient), giving them access to second opinions, and exhausting social supports (e.g. housing them in a safe environment) without imprisoning them.
The bar for being declared incompetent and unable to consent to treatment (which leads to forced psychiatry) is not high enough. Even coming from a psychiatrist, it is effectively hearsay in my opinion. There is not enough due process and outside oversight.
There are real side effects to psychiatry - it's called iatrogenic illness. When somebody is in crisis, what do they prescribe? They prescribe powerful drugs, usually neuroleptics. For example, tardive dyskinesia can affect up to 20% of people who take neuroleptics. It could be permanent - look up YT videos of those afflicted. It's easy to stereotype somebody as mentally ill if they develop TD.
It could be that somebody reacts nicely to the drugs they are prescribed. But what happens when they are released and can't afford treatment or become non-compliant with treatment? It can lead to disastrous withdrawal and terrible side effects, that can result in more hospitalization or a worsening of their illness.
Knowing that, why would you take away somebody's ability to not consent to treatment? Why can't we give them access to intensive therapy, that they consent to, that properly addresses the root causes of their illness and inability to care for themselves? Why do we treat traumatized individuals by inflicting MORE trauma on them? Being kidnapped, imprisoned, and medically raped is traumatizing. Why are individuals not given the option to not consent to medication, but only consent to therapy?
I invite you to look at Soteria Houses, which is a different model of care, that successfully achieves remission in those that are experiencing first-episode psychosis/schizophrenia. If they can achieve remission with little to no psychiatric medication (and likely no life-long prescriptions) in a severe illness, without coercion or locked doors, why don't we give more people the chance to experience that? What if they have the capacity to heal in a supportive environment that doesn't strip them of their rights - an environment that respects their will and autonomy?
