Law Enforcement uses Certified FETI to increase the quantity and quality of the information that they are able to gather from victims, witnesses, and suspects. While Certified FETI is not a replacement for investigations (rather, it is a science-based interviewing methodology), it does maximize and enhance the opportunities for better information collection which, in turn, can and often does result in better overall investigations and outcomes. Additionally, the principles of Certified FETI, including neutrality and empathy, encourage and allow for continued participant engagement with law enforcement throughout the criminal justice system process.
