What 4 States Don’t Permit Insanity Defense?

The insanity defense is a legal doctrine that allows a criminal defendant to claim that they were not responsible for their actions because of a mental disorder.

What 4 States Don’t Permit Insanity Defense?

Insanity defense is based on the idea that some people are incapable of understanding the nature and consequences of their actions, or of distinguishing right from wrong, due to a severe impairment of their mental faculties.

However, not all states in the US recognize the insanity defense.

In fact, four states have abolished it entirely: Kansas, Montana, Idaho, and Utah.

Instead, they may be found “guilty but mentally ill” and sentenced to prison or a psychiatric facility, depending on the severity of their condition and the availability of treatment.

Why Did These States Eliminate the Insanity Defense?

The main reason why these four states decided to eliminate the insanity defense was the public outrage.

For example, in 1982, John Hinckley Jr. was acquitted of the attempted assassination of President Ronald Reagan.

Hinckley was committed to a mental hospital, where he remains to this day, although he has been granted some conditional releases.

Another case that sparked controversy was that of Andrea Yates, who drowned her five children in a bathtub in 2001.

Yates was initially convicted of capital murder and sentenced to life in prison, but her conviction was overturned on appeal.

She was committed to a mental hospital, where she still resides.

These cases, and others like them, raised questions about the fairness and effectiveness of the insanity defense.

Some critics argued that the insanity defense was too vague, subjective, and prone to abuse.

Some also claimed that the insanity defense was based on outdated and unscientific notions of mental illness.

How Do Other States Define and Apply the Insanity Defense?

The insanity defense is not uniform across the US.

Different states have different legal standards and tests for determining whether a defendant is legally insane.

The most common tests for the insanity defense are:

1.The M’Naghten test

This test requires the defendant to prove that they were suffering from a defect of reason or a disease of the mind.

This test focuses on the cognitive aspect of insanity, and is used by about half of the states and the federal government.

2.The irresistible impulse test

This test requires the defendant to prove that they were suffering from a mental disease or defect, and that they were unable to control their impulses or conform their conduct to the law.

This test focuses on the volitional aspect of insanity, and is used by a few states.

3.The substantial capacity test

This test requires the defendant to prove that they lacked the substantial capacity to appreciate the criminality of their conduct.

This test is based on the Model Penal Code, and is used by about 20 states.

It is more flexible and lenient than the M’Naghten and the irresistible impulse tests.

4.The Durham test

This test requires the defendant to prove that their criminal act was the product of a mental disease or defect.

It is the broadest and most controversial, as it does not specify any criteria for insanity, and leaves it to the discretion of the judge or jury.

This test is only used by New Hampshire.

The burden of proof for the insanity defense also varies by state.

In some states, the defendant has to prove their insanity by clear and convincing evidence, which is a higher standard.

Few states, the prosecution has the burden of disproving the defendant’s insanity.

What Are Some FAQs About the Insanity Defense?

Here are some frequently asked questions and answers about the insanity defense:

How often is the insanity defense used and successful?

The insanity defense is rarely used and hardly ever successful.

According to various studies, the insanity defense is raised in less than 1% of all felony cases, and succeeds in only about a quarter of those cases.

Most defendants who use the insanity defense have a history of mental illness and are diagnosed with schizophrenia.

What happens to defendants who are found not guilty by reason of insanity?

They are usually committed to a psychiatric facility or other mental health institution, where they are evaluated and treated.

Some states have a maximum period of commitment, while others do not.

What is the difference between the insanity defense and mental competence to stand trial?

The insanity defense and mental competence to stand trial are two separate and distinct issues.

Insanity defense relates to the defendant’s mental state at the time of the crime.

Mental competence to stand trial relates to the defendant’s mental state at the time of the trial, and whether they can understand the charges and proceedings against them, and assist in their own defense.

A defendant can be mentally incompetent to stand trial, but sane at the time of the crime, or vice versa.

Defendant who is found to be mentally incompetent to stand trial cannot be tried or convicted until they are restored to competence, which may involve medication, therapy, or education.

What is the difference between the insanity defense and diminished capacity?

The insanity defense and diminished capacity are two different types of defenses.

Insanity defense is a complete defense, which means that it can result in a verdict of not guilty by reason of insanity, and the defendant is not subject to criminal punishment.

Diminished capacity is a partial defense, which means that it can result in a reduction of the charge or the sentence, but not an acquittal.

It is based on the idea that the defendant’s mental impairment affected their ability to form the specific intent required for certain crimes, such as murder, but not their general capacity to know right from wrong.

Diminished capacity is not recognized in all states, and is often confused with the insanity defense.
