Brief of Amicus Curiae National Association of Criminal Defense Lawyers in Support of Petitioner.
Argument: Principled rationales for punishment do not justify criminal responsibility for individuals who lack moral culpability. None of the punishment embraced by American criminal law justifies punishing people who lack moral capacity. The insanity defense has protected from criminal punishment individuals who lack moral culpability. Abolishing the insanity defense, as Kansas has done, allows people who lack moral culpability to be imprisoned and executed.
