they were doing; failed to know right from wrong; acted on an uncontrollable impulse; or some variety of these factors” (FindLaw). Whether or not the defendant is guilty or not guilty by reason of insanity, the courts use one or more of the following tests to determine legal insanity: The M’Naghten Rule, The Irresistible Impulse Test, The Durham Rule and The Model Penal Code Test (FindLaw). Based upon the results of these tests can result in a successful defense as well as capacity evidence, volitional control and mental disease evidence (Knoll & Resnick). Although there are tests to determine legal insanity, there is a demographic of people that are often acquitted based upon insanity. The demographic of individuals acquitted from insanity show that “the average defendant is male, between the ages of 20 and 29, unmarried, unemployed, minimally educated and has been acquitted for a violent offense and diagnosed with a major mental illness based upon prior contact with both the criminal and mental health systems” (Lymburner & Roesch). The presence of a mental disease that renders the defendant’s mental capacity of meeting legal criteria for responsibility plays a relevant role in determining criminal responsibility (Lymburner & Roesch). Research provided by Lymburner & Roesch (1997) shows that defendants who are not criminally responsible by reason of insanity were diagnosed with psychotic disorders, many of which were schizophrenics. To dive deeper into the realm of disorders, more than 62% of acquittees were diagnosed with psychotic disorders, 7% with a major affective disorder, 10% were found to have a schizoaffective disorder, 4% were suffering from delusional disorder, 7% had organic disorder, and 10% had a primary diagnosis of personality disorder” (Lymburner & Roesch). One or more disorders may be present within an individual. The insanity defense is similar to the diminished capacity defense in ways that both of these defenses look into the mental capacity of the defendant. The important difference between these two however, is that “pleading with the “reason of insanity” is a full defense to a crime while diminished capacity is pleading to a lesser crime” (Cornell Law).
