1 年The article aptly emphasizes the multifaceted role of lie detectors in criminal investigations. They serve not only as a tool for assessing the credibility of suspects or witnesses but also as a guide in identifying areas warranting further investigation based on physiological responses to questions. This dual functionality, thus, could enhance the effectiveness of investigations. However, another key point to note is the author's caution against viewing lie detectors as an infallible system. Despite their usefulness, it's clear that lie detectors should be used as part of a broader investigative approach, given their inherent limitations and the need for corroborative evidence. Furthermore, ethical considerations surrounding their use, such as consent and the potential for false results, highlight the need for careful application of this tool in criminal investigations.
