"Insanity is defined as a mental disorder of such severity as to render its victim incapable of managing his affairs or conforming to social standards." (Insanity, pg. 1) It is used in court to state that the defendant was not aware of what he/she was doing at the time of the crime, due to mental illnesses. But insanity is a legal, not a medical, definition. There is a difference between mental illness and going insane. Many problems are raised by the existence of the insanity defense. For example, determining the patient's true mental illness (whether they are faking or not), placement of the mentally ill after trial, the credibility of the psychological experts, the percentage of cases that are actually successful, and the usefulness of such a defense.

How would a jury comprised of common everyday people be able to make their decision after sitting in a courtroom listening to each side give persuading facts about how they are correct? Terms like insanity and mental illness have no scientific meaning, causing the relationship between insanity, mental illness and criminal law to be uncertain. As uncertain as the relationship between mental illness and criminal behavior. The insanity defense is impractical and ultimately allows harmful criminals back on the streets, therefore it should be abolished.
