Witness Credibility 1.0

Witness Credibility 1.0 

A police investigator’s job is not to simply collect evidence. Comparatively speaking, that is the early and easy part of the job. The taxing part comes after much of the evidence has been collected. The investigator must then begin to analyze the facts in combination with the evidence to determine if a crime occurred, what methods were used, and to identify the perpetrators. Rarely in an investigation does all of the evidence point solely in one direction, but even when it does, the investigator must still establish probable cause before charges are filed. When there is conflicting evidence, the investigator should carefully review documents, records, witness statements, and other evidence collected to determine which is most reliable and persuasive in helping to describe what actually happened. Witness testimony is considered evidence, but its delivery to the court relies upon the particular witness’ abilities and limitations. This course is designed to help the police investigator evaluate witnesses to reasonably assure their testimony is credible. It describes key ways a witness can confirm or refute their own testimony. Investigators carry a grave responsibility. If a witness is deceptive, and the investigator does not detect it, the witness can destroy the very fabric of the judicial system.
