Crime labs should be an independent force within the criminal-justice system, not beholden to the prosecutor or the defense.
DNA has shown, whether it's the death penalty or not, there are flaws with eyewitness testimony, false confessions and crime labs. We know many more people have been wrongfully convicted than anyone thought.
This is a case where the wrong man went to prison and the real person committed some awful crimes, all because of the utter incompetence of the HPD crime lab. This is the face of the crime-lab debacle. This is the human damage.
In so many instances, doing this DNA testing not only exonerates an innocent person but also helps identify the person who really committed the crime before that person goes out and commits more.
