Michael Bowers has been one one of the heroes to shed light on the bite mark matching fraud. He has personally exposed a number of quacks, and contributed to the National Academy of Sciences report that found no scientific basis for the idea that bite marks on human skin can be definitively matched to one person, to the exclusion of everyone else. Now, two bite mark specialists whom Bowers has criticized are suing him for stating at a conference that they contributed to a wrongful conviction.
