The science of criminal investigation is an intermediary field that scrutinises the findings of either natural or social sciences from an aspect whether or not those findings are later likely to be used during investigations; and if so, in which areas, in what ways, and to what extent; and then upon the examination of legal and professional environments, it will draw up recommendations how to apply effectively those findings. This process can be accelerated more effectively if an independent criminalistics research centre could coordinate certain research activities within the so-called criminalistics research system. As a result, researches carried out methodically, and applicable on a daily basis, may assist investigators during investigations, and at the same time they may ensure the validity of the pieces of evidence that may establish the basis for criminal proceedings.
