Another example, from today's LA Times, from Roger Koppl, director of the Institute for Forensic Science Administration at Fairleigh Dickinson University:
The private forensics lab hired to perform DNA tests in the Duke rape case withheld evidence that exculpated the accused rapists. How could this happen? During the testimony in which this coverup was revealed, lab director Brian Meehan referred to Durham Dist. Atty. Mike Nifong as "my client." Instead of serving the truth, they were serving their "client," the prosecutor's office. Unfortunately, such identification with the "client" is human, all too human. Crime labs should be independent of police and prosecutor, and public defenders should be given greater access to forensic advice and testing. Justice will suffer as long as forensic scientists work for the prosecution rather than the truth.
