Conditions for Using Operational Techniques to Protect State Security in the Light of the Constitution of the Republic of Poland and European Standards

The presented book was created based on a documents analysis - formerly operational, today historical - containing secrets marked with the once highest ? secret of special importance? clause and accounts of witnesses of those times, both officers and victims against whom operational activities were carried out. The monograph contains interesting information about the tactics and techniques of operational control (surveillance). It presents in great detail the four basic principles of operational activities: secrecy, the rule of law, objectivity, economy and the effectiveness of achieving the set goal. Moreover, it discusses the following operational methods: analysis, conversations, legends and legalisation, inspiration, disinformation, operational and technical activities, offensive (agent) activities, controlled purchase and supervision of controlled shipment, combinations, and operational game and planning of actions taken. The author pays special attention to the ? kitchen of operational technology?, i. e. such means of operational technology as: eavesdropping, surveillance (camouflaged and open), surveillance, surveillance (perlustration) of correspondence, operational traps, ? white intelligence? and open sources of information, as well as specialist knowledge.
