    In a handful of occasions such as in an interrogation it seems reasonable enough to lie to an individual in order for them to confess to a crime. A case law that shows this was Frazier v. Cupp in which according to Police Link, “ The case involved the interrogation of a homicide suspect who was falsely told that an accomplice had already implicated the suspect in the killing.” In the case of Frazier v. Cupp kept on getting integrated even after he asked to speak to a lawyer so as a result he ended up doing a written confession where he confessed about being part of the murder that was later used as evidence against him.

  • Making False Confessions

    2223 Words  | 5 Pages

    Psychological research and application have established that it is not only people with learning disability or major mental illness that are susceptible to make false confessions. In order for a confession to be false, a person must either confess to a crime that he or she is completely innocent of or overstate his or her involvement in the crime. False confessions can be either voluntary or coerced. Although it is methodologically difficult to establish the frequency of false confessions, anecdotal evidence such as self-reports and case studies indicate that reported cases are only the ‘tip of the iceberg’. It appears that young people are particularly vulnerable and often make false confessions in order to protect others. Standardized psychological tests have been devised in order to assess personality factors such as suggestibility and compliance that render some people more vulnerable than others. The reason people make false confessions is typically due to a combination of factors such as psychological vulnerabilities, nature of the custodial confinement and the police interviewing tactics. Notorious cases of false confessions which have lead to the wrongful convictions of innocent people subsequently spending years in prison represent some of the worst cases of miscarriage of justice in Britain. One such cases, that of Engin Raghip of the so-called ‘Tottenham three’ will be discussed in the context of admissibility of psychological evidence in order to demonstrate how the judiciary has increasingly come to accept the psychological notion that most people, under certain circumstances, are susceptible to making false confessions.

  • Pathological Liars Are Exists

    I agree when you state that some people can calm themselves. Pathological liars do exist. Lie detectors are not a 100 percent sufficient. Some claim that lie detectors could put an innocent man or woman in jail. There are many tests where an individual’s actually told the truth, but the lie detector results showed that they lied. There are even cases where the convicted claim that they were manipulated. Could that be possible? I’d say yes, it can be possible. However, most cases follow up more evidence to follow its claims. It is rare for someone to be arrested just because of lie detectors. However, failing a test would raise suspicion. In that case, the luck is not on your side if you fail. We always hear people say, “If did nothing wrong,

    When an investigator is conducted an interrogation, they will use every tactic necessary to get the suspect to tell the truth. Also, when there is an interrogation the investigator is not confident that there are insufficient evidence and the suspect’s guilt is not one hundred percent certain, so the interrogator may fabricate the truth or even lie to the suspect to get them to confess (Hall, 2015). The investigators have to use tactics that will deceive the suspect although it is not right to do so because if deception is not used the suspect will not voluntarily say that, they committed the crime. if a suspect commits a crime and writes a statement that was not true we as law enforcement officers we would charge the suspect with falsifying

  • How To Trick A Polygraph

    1200 Words  | 3 Pages

    They tend to question, "If I had to take a lie detector test, could I lie my way through it?" Whether you can trick a Polygraph or not is also controversial, but tends to lean more toward not being true. A lot of experts insist it is highly unlikely that a person would be able to trick a Polygraph because you simply cannot control things such as heart rate and breathing (Robinson, Bryan). It has also been said that you cannot trick a Polygraph because the questions are re-worded and repeated. This way, if you do lie, you have to remember your lie and repeat it while still keeping your heart rate and breathing under control (Palmer, Alun). This tactic, like may questioning tactics, originates from regular interrogations where the subject is asked the same question multiple times. It's harder to remember a lie than the truth. One expert says, "I don't want to say it's impossible, I believe it can be done in a highly controlled environment where the subject has been instructed to lie and has nothing to lose." (Robinson, Bryan). This is also a hard thing to test, because if anyone has ever lied their way through a Polygraph, we wouldn't even know unless it was a controlled experimental environment. These types of experiments would be hard to conduct, and therefore have not been done. This is a problem because part of the reason issues with Polygraphs still exist is because they are hard to
