Eric Clark’s Eye Dropper

His actions were one of the first cases of the Insanity Defense. It brought up discussions about whether or not a defendant has a Fourteenth Amendment due process right due to one's mental stage. Clark, who was diagnosed as a schizophrenic and pleaded on behalf of the insanity defense in hopes of using his mental disorder as an excuse for the crime he committed.

In a 5-4 decision, in favor of Arizona rejecting the plea and sentencing Clark to time in jail. During his time he refused to eat thinking that the guards were aliens in disguise and trying to poison him. Eventually Clark was moved to a high security mental hospital.
