Robert Whitaker has several videos on YouTube and some books about the Psychiatric profession.  The American Psychiatric Association (APA) claims all mental illnesses are caused by a chemical imbalance in the brain, yet there are no testing procedures available to measure brain chemistry.  There is NO scientific data or studies done to support their claim of "chemical imbalance." Whitaker's lectures expose the Big Pharma fraud with SSRI and SSNI psychotropic medications. They simply do not work, yet millions of Americans are taking them because a psychiatrist prescribed them. The AMA has a reference book of conditions and treatments called the Diagnostic and Statistical Manual of Mental Disorders (DSM–5).  No peer reviewed scientific studies are required to add or remove a condition from the DSM-5, they simply make a suggestion at their annual conference, and with a show of hands they vote. This is how your firearms will be confiscated.  The Psychiatric profession is one of the biggest scams being perpetrated on the American people.
