American Psychiatric Association Statement on the Insanity Defense and Mental Illness, by Richard K. Harding, M.D.,
President, American Psychiatric Association:
The American Psychiatric Association hopes that the Yates case will lead to
broad public discussion of how our society and its legal system deals with
defendants who are severely mentally ill. Historically, the insanity defense
was used to excuse from moral culpability, mentally ill people who were so
deranged that they could not tell right from wrong and could not control their
actions. However, reviews of insanity cases show that the more heinous the act,
the less likely that an insanity plea will succeed, despite the disabling
presence of severe mental illness.
Also, the standards for handling mentally ill defendants vary across
jurisdictions. A mentally ill person tried for a capital offense in one state
may be found "not guilty (meaning not responsible) by reason of insanity," while
another person with similar severity of mental illness tried in another state
may be convicted. Some jurisdictions use the designation "guilty but mentally
ill."
Advances in neuroscience have dramatically increased our understanding of how
brain function is altered by mental illness, and how psychotic illness can
distort reality in very subtle ways, to the degree that black becomes white.
Research also has led to development of more effective treatments.
Unfortunately, public understanding has not kept pace with these advances.
A failure to appreciate the impact of mental illness on thought and behavior
often lies behind decisions to convict and punish persons with mental disorders.
The victims of mental illness are sick--just as sick as if they had cancer or
chronic heart failure--and as human beings, deserve humane and effective
treatment for their illness. Prisons are overloaded with mentally ill
prisoners, most of whom do not receive adequate treatment.
Defendants whose crimes derive from their mental illness should be sent to a
hospital and treated--not cast into a prison, much less onto death row.
The American Psychiatric Association is a national medical specialty society
whose more than 36,000 physician members specialize in the diagnosis, treatment
and prevention of mental illnesses including substance use disorders.
