Forensic expertise, as a form of using special knowledge, is one of the most effective ways to establish the truth during the investigation of threats or violence against a law enforcement officer, especially given the often-limited amount of criminally valuable information in such proceedings, which conditions the relevance of this paper.

The most important problems that arise at the stage of assigning expert examinations and can largely affect the quality of expert opinions were identified: violation of the deadlines for assigning expert examinations, incorrect formulation of questions to the expert, provision of insufficient quantity and/or poor quality of materials for research, incorrect definition of the type of expert study.
