Marcus Lentz, CEO of Lentz group, is very critical of the use of lie detectors. This criticism is now confirmed by Joe Navarro, behavior analysis, FBI agent. For Marcus Lentz and his Lentz group, it is important to give evidence at hand to clients that can be used in court as a result of their investigations. It must not be that due to a technicality or not legally recognized methods the client ultimately stands with “empty hands”. Because a significantly high rate of error was demonstrated by approximately 20% for the polygraph, the use of lie detectors in Germany is considered evidence as unreliable and is not offered for this reason.
For Marcus Lentz a decisive reason, critical to the lie detector and do not insert (wirtschaftsdetektei.lentz-detektei.de/news/2013-April/Luegendetektoren-und-die-Wahrheit) in the investigation of the detective agency Lentz. Marcus Lentz advises to in suspected cases on the lie detector refrain and instead using a detective agency through a targeted observation/observation (www.lentz-detektei.de/ 1165dc0e5c9/detective agencies) to obtain evidence, are then also legally permitted and appropriately recycled.

Lugendetekoren in the United States In contrast to Germany are well known in the United States the lie detectors and also recognized – from American movies as well as from American operations by the police, the Government, employers, and so on: a suspected perpetrator sitting wired before the investigator and after each answer beat out pins on the paper. They start to become wildly back and forth to whiz, then the suspect is lying. This device is actually a polygraph, lie detector only in the vernacular”called. Experienced liar, or pathological liars who assume their lie even as avoidable truth, can fairly easily outwit a such polygraph.
With the publication of the book “The little lie detector” by Joe Navarro (mvg Verlag, 112 pages, 4.99 Euro) now also a critical American voice with regard to the use of lie detectors is loud. FBI agent Joe Navarro was for 25 years and worked there for the unit “Behavior analysis”. As an agent for Counterintelligence and counterterrorism, he performed more than 10,000 interrogations. Limits of lie detectors a crucial insight of his observations and experiences is that it is difficult to differentiate whether certain behaviors are the result of a lie or alone of stress as a mere result of the Verhores. In recent months, Harold Ford Jr, New York City has been very successful. Both the people and the lie detectors fail due to insufficient differentiation according to Navarro. Therefore, a basic prerequisite is to debunk illusions, carry out the interrogation in a relaxed situation. Who loudly screams around or in the interrogation is pressuring does everything wrong according to Navarro. Also can you rely according to Navarro not only on individual behaviors, but must pay attention to face, torso, arms, both legs and feet. In the book “the small lie detector”has put together Navarro 216 gestures, which were good indicators of nervousness, malaise, deceptions or even authenticity during his FBI time. It is to keep in mind that when people with high social status, or chronic liars is accordingly more difficult to expose deceptions, because these people are used to occupy the space, to be observed and quickly can regulate their reactions. Observations instead of lie detectors confirm the thesis of Marcus Lentz, after the important decisions based on hard facts and not due to inaccurate analyses should be taken this knowledge and voices from the United States. In his opinion the specific, serious and competent observation is the far more appropriate calculation method as the use of lie detectors. Looks like the corresponding observation at the Lentz Detektei in detail is under
