Critics on insanity defense
a) The key terms in the various insanity tests are so vague as to invite speculation and intuitive moral judgements in the guise of factual determinations;
b) There is little or no basis in psychiatry for allowing expert witnesses to testify—as they often do, in conclusory terms—concerning the differentiation between persons who are personally blameworthy and those who are not;
c) It is therapeutically more desirable to encourage treatment of persons as actors responsible for their conduct, rather than as involuntary victims ‘playing a sick role,’
d) The insanity defense discriminates against persons who commit crimes because of influences on their personalities other than mental disease or defect.
What it means when someone is found not guilty by reason of insanity?
treatment or institutionalisation
Guilty but insane
the defendant would undergo a psychiatric examination and a court hearing to determine if he were still suffering from a mental disease. If so, he would be committed to a mental hospital. When in the opinion of the hospital staff he had recovered and could safely be released, the court would have another hearing. If the court was in agreement with the psychiatrist’s opinion, it would then order the defendant’s discharge.
Guilty but mentally ill
who had an understanding of what he was doing at the time of the crime but was hindered to some degree by a mental illness.
he convicted defendant would receive a sentence under the applicable criminal law, but would also receive a psychiatric evaluation. If he still suffered from a mental illness, he would be institutionalized. If his mental health was restored within the time period of the criminal sentence, he would then go on to prison. If the mental illness and institutionalization were to continue beyond the length of criminal sentence, a new civil commitment hearing would have to be held to insure the constitutionality of further detention.
