Police efforts to counter such crime require scientific assessments and theoretical support; because of this, the Slovak police academy has begun a special research project called "Constitution Police Security Science." The primary aim of the project is to give the police force and security services a theory, methodology, a system of effective investigative method, and a clear and accurate conceptual apparatus pertinent to the investigation of sophisticated crime. Police security science aims to remove police policies and procedures from subjective assessments and opinions and place them in scientifically based research. This will lead to the development of police practices and policies that promise to be effective in countering various types of crime. The structure of police security science consists of disciplined, standardized police practices for preventing and investigating crime. This involves theories of crime investigation, the collection and analysis of evidence, and crime prevention. In terms of methodology it consists of individual methods for various kinds of crime investigation, individual methods for processing various kinds of cases, and methods for various crime-prevention activities.
