It is almost amusing to read some of the comments here. The basic knowledge about mental illness seems to be almost completely missing in many comments. Having a diagnosis that is within the realm of psychiatric disorder is not the same as legally insane. In fact, mental health professionals struggle with testimony on court, where lawyers and judges need information that follows the terminology and criteria of the law, which is vastly different from the nomenclature and labels used by the professions. Example: psychotic is not a legal term. Insane is not a clinical one. Someone suffering from anxiety carries a clinical diagnosis of a psychiatric nature. That does not qualify to be exempt from responsibility for the commission of a crime, or from standing trial.
Before making these bold and general statements, a bit of professional study would be worthwhile. Without that, the statements are rather close to gibberish.
