Mcnaughton's Defense: The Insanity Defense
The Insanity defense first came into England’s radar when Daniel McNaughton, who attempted to murder, Prime Minister Robert Peel. McNaughton Rule became a common law test to determine criminal liability in relation to mentally disturbed defendants. Another notable case is that of Reagan, John Hinckley who in 1981 attempted to assassinate the president.
The insanity defense is not covered as its own constitutional right, although it faults under the due process clause in the 5th and 14th amendments. The states define their own elements for what constitutes insanity, using the common law as a guideline. Mens rea—Latin for the “guilty mind” — is one of the necessary elements for insanity. If found incompetent, the person is usually charged to

    The Insanity Defense

    The insanity defense is one of the several legal questions that might be raised in a criminal case. This type of defense in a criminal case focuses on the defendant’s cognitive and mental state at the time of the offense. Due to this speculation, the questions focuses on whether the defendant is criminally responsible for his or her behavior due to the mental state at the time of the offense (Hugaboom, 2002). Also, additional questions are required to determine psychological evidence might also be included in the case. The psychological issues will include the defendant’s competency to stand trial, the mental conditions that are relevant in consideration of the sentencing, and competency to waive rights. According to Hugaboom (2002), insanity…

    The McNaughton rules were used to decide if a crime was committed by someone who was deemed to be insane at the time of their crime. McNaughton rules were so named after Daniel McNaughton who attempted to kill the current Prime Minister as he had an imaginary grudge against him but for no real reason, just his “state of mind” at the time had led him to believe that so he was found “not guilty by reason of insanity”…

    Eddie Routh Case Study

    The insanity defense is only raised in 1% of cases and then only successful 25% of the time it is used; although its rarity, the legal court has very detailed rules. Most rules describe not guilty by reason of insanity as not being aware of what you were doing in that exact moment. Adam Banner suggests that the Eddie Routh case had an accurate ruling of guilty because of his claim that, “...the disposition is ‘not guilty by reason of insanity’. It is not ‘not guilty by reason of mental illness’,”. Only Mental Health America would disagree, stating, “The Court has indicated that states may be required to provide at least some minimal defense based on mental illness,”. Coincidently, these changes have not been made thus…

    According to our textbook, Wrightman’s Psychology and the Legal System, M’Naghten had paranoid delusions. He believed that the Prime Minister, Robert Peel, was aligned with the Tory Party in a conspiracy against him. He tried to run, but when that didn’t do the trick, he returned and stalked the Prime Minister. He later shot a man, who he believed to be the Prime Minister, but he actually killed the private security of the British Prime Minister. He was charged with murder, but after a couple of days of medical experts testifying, he was found not guilty by reasons of insanity (NGRI). (Greene & Heilbrun, 2011 pg.210) Our text describes the M’Naghten rule as “The jury ought to be told in all cases that every man is to be presumed to be sane, and to possess a sufficient degree of reason to be responsible for his crimes, until the contrary be…

    The insanity defense should be allowed for those with a mental illness when they commit a crime since they are not in control of their actions. “If a person really does have mental incapacity, and it will be considered that his condition has caused him to commit a capital crime, which means the defense could save his life. Put in mind that a capital crime carries a punishment of eventual death. However, being found not guilty because of insanity means that a capital punishment is out of the question. It could mean that the accused would just be housed at a professional mental health treatment center. Though it might not be jail, still it gets him off the streets,” (12 Profound Pros and Cons of the Insanity Defense [Web log post]. (n.d.). Retrieved May 16,…

    When I try to reason how people would interpret the insanity defense, it reminds me of the common misconceptions that juror's have of the defense itself. In the textbook it examines the various insanity defenses and the courts perception of the defenses, while in the video, Lionel tries to examine peoples reactions to the insanity defense. In the textbook while it went to how the defense's many interpretations have effected case outcomes, Lionel's video tries to clarify that how average Americans cant handle the horrors they see when looking at the crime scene photo's and then trying to decide that the defendant could be considered for a insanity defense.…

    For starters, the expression, the courtroom definition, and the psychiatrist term of the word “insanity” are all different and all have different connotations. In order to be considered insane in today’s court, you have to be completely separated from reality. As described by Vaknin, “A perpetrator should go unpunished - and be hospitalized instead - only if he is found to be completely divorced from reality by diagnosticians from both sides, a far cry from today’s insanity defense” (2). To prove that a suspect is in fact separated from reality, a few things have to be proven. The first thing to be proven is if the suspect had a diminished capacity. Macbeth showed that he was mentally impaired when he brought the daggers back instead of putting them with the guards and smothering them with blood. Although he knew that he was killing, he was not stable enough to carry out the entire crime. After the first crime, he could not control his behavior anymore. It became out of hand and he wasn’t able to control it anymore. He felt the urge to kill; which proves that he had an irresistible impulse which could no longer be controlled. In a way, he also lacked criminal intent. While he intended to kill, he did it because he believed that killing the king was what he was meant to do.…

    To be considered insane and mentally unstable, I believe a criminal defendant must be unconsciously aware of their actions and there should be no prior intentional plan planned out to commit a crime or felony. However in some cases, criminal defendant has used the insanity plea as a defense, in which they have thought out and did intend on executing the crime as a result of mental illness. Even though some people are right about abolishing this legal defense because some defendant may take this as an advantage and hopefully be declared as not guilty, I still believe that the insanity plea is still an essential part of a rational criminal justice system. According to Psychology Today, the insanity plea has been used less than 1% of all the…

    Actus rea and mens rea are both important elements to convicting anyone for any crime. The actual commitment of a criminal act is actus rea. The guilty or criminal mind state is mens rea. Despite the fact that both actus rea and mens rea do not have to exist a conviction is still very feasible. When a criminal act is committed and the individual does not have to mens rea or guilty mind in some instances without the required mental state no crime is committed. Persons incapable of entertaining the required criminal mind because of legal insanity have not committed a crime. Working with individuals who have been diagnosis with mental retardation has really opened my mind to the element of mens rea when the individual has done something illegal. Some of the individuals have it in their mind that because the have been diagnosis with mental retardation they can not be held responsible for the criminal act they may commit or have committed, I have even heard many of the individuals say it. Does this mental state qualify them of the required state of mind for conviction?…

    In 1843 there were guidelines made for evaluating criminal responsibility for defendants claiming to be insane by the British courts. This defense became known as M’Naghten Rules. Daniel M’Naghten was a Scottish woodcutter who murdered the secretary to the Prime Minister, Sir Robert Peel, when he was trying to assassinate the prime minister. M’Naghten believed that the prime minister was to blame for all of his problems. A jury acquitted him after they heard testimony by nine witnesses who all said he was insane. He was found not guilty by reason of insanity. The common law courts said that a person should not be held responsible for his actions if due to his mental disease or defect, he did not know that his act would be wrong or did not understand the nature of his actions. The M’Naghten rule was embraced with almost no modification by American courts and legislatures for more than 100 yrs, until the mid-20th century. In 1998, 25 states plus the District of Columbia still used versions of the M’Naghten rule to test for legal insanity. The key is that the defendant could not appreciate the nature of his actions during the commission of the crime.…
