legal insanity
Courtroom mental defense
Legal insanity is a defense in criminal law holding that a defendant cannot be held responsible for a crime if, due to mental illness, they couldn't understand what they were doing or couldn't distinguish right from wrong.
The standard varies by jurisdiction but generally requires more than mental illness alone—it demands a fundamental break from reality at the time of the act.
The jury rejected the legal insanity defense, finding that he knew his actions were wrong.
