The profession of “detective” is one of the most attractive. Sherlock Holmes, Hercule Poirot, Lieutenant Columbo, and other heroes of detective movies were amazed by their intelligence and easily solved even the most complex crimes. Not surprisingly, many would like to follow in their footsteps. This specialty officially appeared in 1967. At that time, the European Community issued a directive that defined the rules and regulations of the business. This included detective work. In Europe and the United States, a detective is a police officer. The essence of his work is to conduct investigative activities and find criminals. If this specialist works independently, he is called a private detective. The profession of a private detective does not exist in all countries. The fewer the freedoms and rights of citizens, the more restrictions on professional activity. For example, in Mali, North Korea, and other non-democratic countries, it is forbidden to engage in private detective investigations.
