Do you think that chain of custody issues should be ignored if a convicted felon asks for DNA testing with techniques unavailable at the time of the initial trial, and why?
Chain of custody issues should never be ignored as evidence can then be tainted. If the DNA testing shows that the convicted felon was innocent of the crime and the chain of custody was not tainted, the felon should be set free. If, however, there is no clear chain of evidence custody, more investigation is needed to determine if the felon was wrongfully convicted. Criminal evidence is too easy to tamper with and too easily used in the wrong way if it is not kept clean with clear chain of custody. I am in favor, however, of prisoners being able to ask for DNA testing if reasons for that retesting exist.
