The important role of improving the activities of all law enforcement agencies depends on the scientific level of their organization. An essential part of the methodology for the investigation of any crime is the element devoted to the specifics of investigative tactics, a special place among which is occupied by an investigative examination of the scene of an incident, from which an investigation usually begins. Investigative actions (in particular, investigative examination) carried out under low air temperature conditions have their own significant features that require separate study. This paper deals with the peculiarities of carrying out a type of procedural investigative action, such as examination in the Arctic conditions (low air temperature), gives practical recommendations to law enforcement officers on how to act in conditions related to adverse weather situation (low temperatures, shortened daylight), deals with the peculiarities of work in these conditions with traces of hands, feet, vehicles, burglary; special attention is paid to the peculiarities of working with odor and shooting traces; special attention is paid to the peculiarities of work at the scene of corpse location and of work with blood traces. General scientific methods were used as the research method - analysis, synthesis, determination of cause-effect relation of the phenomena in conditions of low temperature, and also the philosophical law which assumes differentiation of scientific knowledge about scientific grounds of tactics of procedural investigative actions in combination with the necessity of integration of the received knowledge with other sciences (logic, criminal procedure law, medicine).
Forensic dermatoglyphics describes the study of the features and characteristics of the prints and volar surfaces of the hands and feet, as well as the flexors, functional folds, and skin of the person as a whole. It also studies the traces of them found on various items during investigative and search activities in order to determine the character features and body specifics using genetic, national, and geographical traits. Serving as a background for this paper is the fact that in 2016 dermatoglyphics was deemed a pseudoscience. Due to this, it was decided to study the current problems of dermatoglyphics, particularly forensic dermatoglyphics, using proven methods of scientific research as the basis. These include the necessary differentiation of scientific knowledge in combination with its necessary integration with other sciences. At the same time, the method of deduction allowed us to draw conclusions about the unfoundedness of forensic dermatoglyphics as a field of science, at least in its current state. This paper relied on data obtained by various authors. However, forensic dermatoglyphic research is currently being carried out in small groups of test subjects which cannot be a reliable base for scientific statistics; it was concluded that further research focused on developing ways of using dermatoglyphic data in court and investigative practices can only be carried out on a significant empirical basis by creative teams which are made up of representatives of anthropology, doctors of various specialties, primarily, dermatologists, and criminal lawyers. Only this approach will help solve the question in the future about whether or not forensic dermatoglyphics can become a field of science.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
