This is an automatically translated description

Continuing the topic of detective art, the author describes in an accessible form various ways of documenting criminal activity. They are called detective operations because of their content and purpose. They can be used not only to collect evidence but also to verify the accuracy of the information provided. Scenarios, algorithms and tactical techniques for conducting search operations are particularly useful for organising modern social life. They can be used by managers, owners of enterprises and organisations. The undoubted benefit of search operations will be manifested in the activities of law enforcement officers and lawyers of any field of law.
