    Introduction Nonverbal behavior is the important part in conversation. Even though our communication is based on words, but there are still many things that cannot be explained by words and need to be explained by using nonverbal behavior.

    There is no fail-safe way to determine if a subject is lying, however it has been established that there are nonverbal actions that are related with a suspect’s dishonesty (Virij, 2008). Additionally, behaviors will differ across deceptive situations; as a result it is imperative the interviewer notes down changes in behaviors in response to the questions. According to Hoffman (2005), there are a series of verbal and non-verbal behaviors that may indicate dishonesty, examples for non-verbal behaviors include (1) sagging over or slanting back in the chair, or a constant shift in position in the chair; (2) placing the hand over the mouth to muffle words or hide expressions, arms crossed with the thumbs extended; (3) constant movement of legs and feet; (4) having his or her head down can indicate a negative attitude or submission, head nodding or head shaking (Hoffman, 2005, p.…

    When charged with a crime, many people panic and, in an attempt to curry favor with prosecutors, give away some of their most fundamental rights. To help you avoid serious mistakes, some of which could have serious, long-reaching consequences, Tom Ganim at Ganim, Ganim & Ganim, P.C. in Bridgeport, CT, recommends hiring an attorney who will ensure that the process is conducted fairly.

    The U.S. Supreme Court has made decisions to allow police officers to use deception during custodial interviews of suspects per case law Frazier v. Cupp, 1969 and Oregon v. Mathias on, 1977. Supportive decisions of deception has been made also in the State Court level per State v. Nightingale, 2012. Deception during investigations does not mean a case to be solved by “whatever means necessary,” as the suspects have their civil rights. However, I do believe the deception and baiting a suspect during investigation and in custodial interviews, is a tool necessary to pursuant of solving a case. There has to be reasonable and prudent justification to use deception in relation to the case under investigation and it should be proportional.…
