Police and private security officers' handling of statement-taking and interviews with crime victims, witnesses and suspects is generally a critical element in investigations. Although conventional procedures are applied in such situations, there is a lack of systematic studies on statement-taking techniques. 

To be effective in their work, police and security officers need to master certain techniques that go beyond mere experience or intuition, to conduct interviews effectively and detect possible deceptive behaviours. 

This course includes demonstrations of statement-taking techniques in line with the training system used by the National Academy of the FBI.
