Signs a Suspect is Lying

     A lying suspect [under interrogation] will speak in fragmented or incomplete sentences such as "It's important that...." He also may feign a memory failure when confronted with a probing question or in responding to a direct accusation of lying. The person will respond with a half-lie, such as "I don't remember," "As far as I know," or "I don't recall;" or, the person my try to bolster his answer with such phrases as "To be perfectly honest with you," or "To be quite frank." [When politicians speak, they are always being "frank."]

     The more sophisticated liars may use the same type of evasions, but they usually plan beforehand so that their answers include a protective verbal coating, such as: "At this point in time," If I recall correctly," "It is my understanding," " If my memory serves me right," or "I may be mistaken but...." By using these tactics, lying suspects seek to establish an "escape hatch" rather than risk telling an outright lie.
