Everybody has weak sides of his own. It is a big mistake to believe that perfect systems exist in this world. Psychiatry has also its flaws. Of course, psychiatrists don't disclose skeletons in their cupboard, but there are some.
Let's take a close look.
I have no idea who it works in US, but in some countries, in Russia for example, cops detaining someone need his signature verifying their report listing his wrongdoings. For example, someone was
detained in a subway station being completely drunk. Cops made the report and brutally beat this guy demanding him to sign their bloody report, because he denied to do this. He signed finally, and the report became 'legal'.
This can be funny, although the story itself is really tragic, but cops have less power than psychiatrists, because I've never heard that anyone has ever signed any reports being interviewed by psychiatrist. They don't torture their victims at the first interview because as far as I understand they are been blindly believed by courts and other judicial and law enforcement agencies!
I bet there is no any control in psychiatrists room whatsoever. No video cameras, no microphones.
So theoretically they can write down whatever they want or interpret an interviewee speech according to a particular diagnosis strengthening some symptoms, weakening others etc. Comparison of visitors real words and psychiatrists reports may become a great scandal, because potential patients have no means to check what psychiatrist write in their papers.
The situation I've just outlined is extremely disgusting, because even in the dungeons of most brutal regimes secret police officers always demand signature as the sign of their victims agreement.
But the strength of psychiatrists is also their weakness. Theoretically it is possible to oppose their words in a courtroom or in other legal agencies, just saying the plain truth: 'This doctor has never shown me any records of my interview, I've signed none of them, so I'm not quite sure that his records objectively cover my mental state'.
This is a big deal, it is related so constitutional rights of every person in every country, it is related to the principle of informed consent practised in many societies etc. Of course a judge can reply that he has no reasons to disbelieve psychiatrist. This is a very powerful argument I don't know how to oppose at the moment. But I think that I've shown that psychiatry has some significant weaknesses from the legal point of view.
PS. I wonder what will happen if a visitor entering psychiatrist's room will ask first: 'Will i be able to read, sign or disprove your record of our conversation'?
