Part 5/8:
While acknowledging the utility of polygraph testing, the examiner openly discusses its limitations, especially the subjective element involved in interpretation. He notes that polygraph results are not always admissible in court because they can be manipulated or misinterpreted.
He recounts how he has used lie detection informally on staff members—such as asking them to hide his phone in different locations and subsequently observing their reactions—highlighting the technique's reliance on behavioral cues rather than formal testing. Interestingly, all three staff members failed his informal 'test,' which he considers revealing of their discomfort or guilt.
