Tactical and Forensic Problems Associated with the Emotion of Fear in the Investigation of Terrorist Act Crimes

The paper examines the manifestations of the emotion of fear of participants in a terrorist act in a crime model and investigation situations. When examining a crime scene and investigating a terrorist act, it is necessary to analyze the behavioral scenarios and reactions to danger not only of victims and witnesses, but also of criminals, since their behavior is also conditioned by a reaction to fear, namely the fear of death and the desire for it. The methods of committing a terrorist act make fear its instrument and goal during and after the commission of the crime. The consequences of experiencing emotions complicate work with eyewitnesses of a crime due to the phenomena of amnesia and the unwillingness of victims to remember what they experienced, which is aggravated by post-traumatic stress disorder, determining the investigator to more thorough work on studying the personality of the person being interrogated, diagnosing his condition, and also involving specialists in investigative actions. Forensic technical and tactical methods in the investigation of terrorist act crimes are prioritized by ensuring the safety of the investigator to a greater extent than in other types of crimes, due to the presence of a direct threat to life in the initial stages of the investigation.
