Interrogator


Interrogation (also called questioning) is interviewing as commonly employed by law enforcement officers, military personnel, and intelligence agencies with the goal of eliciting useful information. Interrogation may involve a diverse array of techniques, ranging from developing a rapport with the subject, to outright torture.

There are multiple techniques employed in interrogation including deception, torture, increasing suggestibility, and the use of mind-altering drugs.

A person's suggestibility is how willing they are to accept and act on suggestions by others. Interrogators seek to increase a subject's suggestibility. Methods used to increase suggestibility may include moderate sleep deprivation, exposure to constant white noise, and using GABAergic drugs such as sodium amytal or sodium thiopental. It should be noted that attempting to increase a subject's suggestibility through these methods may violate local and national laws concerning the treatment of detainees, and in some areas may be considered torture. Sleep deprivation, exposure to white noise, and the use of drugs may greatly inhibit a detainee's ability to provide truthful and accurate information.

Deception can form an important part of effective interrogation. In the United States, there is no law or regulation that forbids the interrogator from lying about the strength of their case, from making misleading statements or from implying that the interviewee has already been implicated in the crime by someone else. See case law on trickery and deception (Frazier v. Cupp).

As noted above, traditionally the issue of deception is considered from the perspective of the interrogator engaging in deception towards the individual being interrogated. Recently, work completed regarding effective interview methods used to gather information from individuals who score in the medium to high range on measures of psychopathology and are engaged in deception directed towards the interrogator have appeared in the literature. The importance of allowing the psychopathic interviewee to tell one lie after another and not confront until all of the lies have been presented is essential when the goal is to use the interview to expose the improbable statements made during the interview in future court proceedings.
