I don't agree with your observations. The police and other authorities look upon no one as "infallible."
Psychiatrists are responsible to licensing boards and often state boards/authorities, let alone insurance companies. There are checks and balances in place.
There are sections of the Ross Institute website that reflect many psychologists and psychiatrists being sued and having their credentials taken away.
The CCHR had nothing to do with any of those cases.
I certainly would not recommend working with Scientology or an organization it apparently controls such as the CCHR under any circumstances.
Again, they have their own agenda and deeply troubled history.
There are other avenues, support groups and options without becoming involved with Scientologists.
However, if you wish to be a Scientology/CCHR supporter that's certainly your choice.
Are you opposed to psychologists and psychiatrists as a profession? Do you think they help anyone?
