Would there be any need for state laws in a LFC society?
Here is a somewhat specific example regarding Insanity Law:
Four states (Montana, Utah, Kansas, and Idaho) have entirely abolished the insanity defense, and a majority of the states that still allow it place the burden of proof on the defense, usually by a preponderance of the evidence standard. The federal system and Arizona require that the defense prove insanity using the higher clear and convincing evidence standard… Clear and convincing proof requires that the truth of issue be highly probably, and this standard is greater than preponderance of evidence and less than proof beyond a reasonable doubt…
The guilty but mentally ill (GBMI) verdict is an attempt to bypass the definitional morass of insanity. The GBMI verdict is permitted in 13 states, and is usually an additional alternative verdict to the three more standard options of guilty, not guilty, and NGRI. Only Utah has adopted a GBMI verdict without also having an NGRI statute…
My understanding is that state laws can override federal law (which is what’s happening above), but that seems like a bad thing, since it allows different states to use different tests and standards to determine if someone’s legally insane. Wouldn’t it be better to have federal laws that apply to all states?
