since I have never done drugs and not had mental illness-
how do mentally ill / high on drugs people know enough to understand "now I take a knife and I can then kill a human being by slashing their throat"?
if they can still reason and understand concepts such as weapons and death- how is being high or insane a defense to the crime?!
how can John Hinkley be "criminally insane" but still have plotted out how to get a gun, how to track President Reagan, knew he was trying to murder someone. sounds like they still understand what they are doing is wrong.
Due (in part) to backlash against the bogus insanity defenses that worked for John Hinckley, Jr. (as well as the infamous "Twinkie defense" from the San Francisco city councilman who murdered Mayor Moscone and Harvey Milk), most of the examples you cite would not be the basis of a valid insanity defense nowadays.
Attempts to escape, conceal the crime, or an understanding that one's actions are illegal are generally enough to meet the definition of legal "sanity". Everyone would recognize that on one level, say, Jeffrey Dahmer was completely out of his gourd; most of us don't kill and eat people not because we are deterred by the law but by
why in the hell would you eat someone? Nonetheless, Dahmer was sane in the eyes of the law as regards criminal culpability.
What would rise to the level of being legally insane is a degree of mental illness that makes the person unable to understand that their actions were not legally justifiable.
Example: If a crazy person thinks that someone is implanting cancer causing rays in his brain and attacks that person, then tells the cops it was self defense, that could qualify as legal insanity.
ETA: Almost certainly this will not apply to Reiner's son. He is going to die in prison unless he unalives himself before he gets there.
