There are a number of countries that believe in the detector de mentiras test and in case you were wondering whether or not the results of a lie detector test can be trusted and can be used in court then you need to understand that in Madrid it is legal to use this test to convict a criminal based on the results of a polygraph examination. 
As long as this test is conducted under expert supervision, the results are highly accurate and you will never have to worry about getting a false result. A lie detector test is much better in comparison to constantly questioning and torturing someone to get out information. It can also be used in personal matters such as a property case or a divorce where it is otherwise impossible to prove that one of the partners has been unfaithful. It is easy to get this test done once you have a letter from the court.
One of the things that every business owner dreads is losing out to their competition. There are a number of businesses that have certain trade secrets that keep them ahead in the market place. These trade secrets are shared only with the family members and certain old employees that they trust. One of the things that most businesses look to do is buy these employees.
This can be done in the form of bribes or even in the form of threats. If you feel that your employees are in touch with someone from the outside or they are behaving suspicious, there is no point in confronting them. This would only make them even more alert. Subjecting these employees to a lie detector test is the best way to get information out of them. No one can lie to a lie detector test and get away with it.
