In February, a Mississippi judge released two convicted rapists of children, who had each been in prison for more than 12 years, based on DNA. The men had been convicted primarily by the "bite mark" analysis of since-discredited dentist Dr. Michael West, who used iridescent lights and yellow goggles to demonstrate that scratches on the victims were bites by the two men. Subsequent independent analysis identified the scratches as scratches, perhaps even made by West himself, according to a director of the Innocence Project. West is a favorite colleague of medical examiner Steven Hayne, who seems always to find evidence of guilt of anyone charged by district attorney Forrest Allgood, according to a Reason magazine investigation. West's bite "technology," in particular, has been widely ridiculed by forensic professionals.
