Sgt. Paul Carroll Consulting & Training

Eyewitness Identification Course

Eyewitnesses frequently play a vital role in uncovering the truth about a crime.  The evidence they provide can be critical in identifying, charging and ultimately convicting suspected criminals.  That is why it is absolutely essential that eyewitness evidence be accurate and reliable.  One way of ensuring investigators obtain the most accurate and reliabe evidence from eyewitnesses is to follow sound protocols during their investigations.  Recent cases in which DNA evidence has been used to exonerate individuals convicted primarily on the basis of eyewitness testimony have shown that eyewitness evidence is not infallible.

Sgt. Paul Carroll was a Planning Panel Member of the National Institute of Justice Eyewitness Evidence Technical Working Group that developed such protocols.  This Eyewitness Evidence Technical Working Group was made up of law enforcement and legal practicioners, together with social science researchers from across the United States and Canada.  The eyewitness identification protocols and other important details such as understanding human memory, cognitive interview techniques and double blind procedures, are covered extensively within this course.
