An editorial by Dr. Cyril H. Wecht, past president of the American Academy of Forensic Sciences, notes that crime labs are overwhelmingly backlogged with work and that deficiencies of personnel, space and equipment in forensic science labs often lead to shoddy practices and erroneous test results, as recently exemplified by the problems uncovered at the Houston Police Department DNA lab (see below). Dr. Wecht notes:
There can be little doubt in the minds of trained, experienced forensic scientists that testing defects, backlog pressures, inadequately qualified personnel, and prosecutorial bias exist in many other DNA labs even though they have not yet been uncovered and publicly reported.
Until these glaring deficiencies are identified, objectively reviewed, and carefully corrected, society cannot expect that justice will be served.
State lawmakers should carefully scrutinize DNA labs that use inferior testing methods that lead to inaccurate results. An immediate freeze on executions is essential until scrupulous federal and state reviews of all DNA labs have been accomplished. This is the only just way to proceed. Close attention to this critical problem will not only lower the risk of executing innocent people, it will also facilitate the capture and conviction of the guilty. (Emphasis added).
