In this new book written by Brandon Garrett, a law professor at the University of Virginia School of Law, explores the circumstances surrounding 250 wrongly convicted individuals exonerated by DNA. In 76% of the cases eyewitnesses wrongly identified the accused. Furthermore, " Garrett found invalid forensic testimony in 61% of the trials where an analyst testified for the prosecution, including overly confident claims of matching bite marks, shoe prints and hair samples." In 16% of the cases the accused had falsely confessed.
