Certainly the prisons hold dangerous people who are guilty of the crimes of which they were convicted and most of those sentenced to death committed heinous acts. To a person sitting in jail sentenced to death who knows they are innocent would welcome the idea of an independent agency validating the forensic evidence by testing it again. Thanks to the power of DNA evidence, media coverage and the innocence project movement, there is awareness that wrongful convictions occur. Evidence does get contaminated, even though in all cases evidence should be properly retained and easily retrieved. Forensic analyst makes mistakes that could result in improper and invalidated results which are the leading causes of wrongful criminal convictions.
