The article deals with the peculiarities of tactical techniques for conducting interrogations on extremist crimes committed on the Internet. The Internet space acts as a social environment that is congruent (attractive) for adherents of extremist activities, where their leading characteristic is a focus on atypical, non — normative, asocial behavior. Tactical interrogation techniques create conditions for obtaining evidence about the circumstances of the case: whether there was a call to violence, whether violence is justified, what is the content of the materials presented in the network, what means (posters, leaflets, etc.) were used. When conducting an interrogation, the use of psychological influence techniques makes it easier to obtain criminally significant information. For individuals who commit crimes of extremist orientation, taking into account the typification of personal characteristics (idealistic, adventurers, non-normative), some effective tactics are described (egress to emotions, naked aggression, exchange of positions, intervention of an authoritative third, etc.) with an approximate list of questions. Techniques are designed to achieve mutual understanding between the investigator and the interrogated, in which the latter, regardless of the current situation, cooperates with the investigator and provides information about the circumstances of the case without distortion or concealment.
