Yeah we already do have a somewhat similar mechanism for legal insanity or incompetence to stand trial the two are separate things - technically someone who was so out of it they think their victims they killed were demons wearing human skins and everyone else is crazy for not seeing it and a dementia afflicted serial killer may or may not have been culpable at the time of crime but both aren't suitable to stand trial now.
