The examination of legal systems, including the so-called system of police law, indicates that there are many systems and institutions with authoritarian competence and power to control and use repressive measures. They have at their disposal many tactical and technical means that can be used unofficially and out of trial procedure (surveillance, phone-tapping, controlled purchase, use of legalization documents, etc.). Some organs sometimes have the same tasks and powers. There is also a tendency to establish new units although some of their tasks can be successfully fulfilled within the scope of activities of the already existing organizational units of the state. For common fear of terrorism, new ideas in the field of new surveillance techniques are invented across the world, including Poland. Public opinion was alarmed by the increasing imbalance between the aspiration of governments to protect public safety and the necessity to protect civil rights and freedoms. Due to that, the question about the appearance of symptoms of a police state development seems to be justified
