To successfully mount the defense of insanity in Florida criminal courts,( Miami and Fort Lauderdale), the accused (arrested) defendant must prove that the/she was insane at the time the criminal act occurred. Insanity before or after is not a defense. Further, that the mental deficiency must be related to the specific criminal charge. Insanity in general is not a defense to an arrest or criminal law prosecution in South Florida criminal courts. In Florida criminal law the word “sanity” addresses the issue of one’s ability, at the time of the act, to understand and distinguish the difference between right and wrong. This is called the McNaughton rule. The rule goes to the ability to understand the nature and quality of a defendant’s act, and its consequences. In South Florida criminal law insanity goes to one’s capacity to distinguish right from wrong.
