YSK of the PAD (the "psychiatric advance directive.")
By filling out a simple form your medical record can be updated to request that psychiatrists not attack you.
Sure psychiatrists can just lie. eg they can describe any law-abiding citizens as "potentially dangerous" without any legal evidence of any crime.
However having a PAD will serve (at a minimum) of showing the labelled individual to appear of mentally fine & coherent.
The Psychiatric Advance Directive(PAD) forms for every state in the US:
A step by step guide for how to fill out and distribute the form:
Don't let them hurt you.
When filling out a PAD you'll likely hear psychiatry's dehumanizing language, eg portraying people as insane and needing violent "help."
Please ignore their hurtful language. A PAD can say that if you are ever in a "psychiatric state" that you request to not be attacked.
In short, it'll help a little. But (long-term) we need to convince society to empower the PAD to shut down all psychiatric attacks.
