Exactly.
How reliable is forensic science?
Judge Harry T. Edwards explains.
"I think I, and many of my colleagues, assumed that the forensic disciplines were based on solid scientific methodology, were valid and reliable. I don’t think that we assumed that there was anything seriously amiss.
"We assumed there might be mistakes, but I don’t think that we had been forewarned in any way that there were the serious problems that the committee uncovered. …"
"If some people are saying it works because we’ve gotten convictions, that is to say nothing more than juries and judges have believed that experts knew what they were talking about. And so they bought it and they convicted. That’s not proof that the discipline is undergirded by serious science...."
"For example, there was a report on bite marks recently, … saying there’s just no science to support a lot of what the so-called experts have been assuming with respect to the validity and reliability of bite marks. …"
"I think there have been enough acquittals, post-conviction releases in hair cases, and there has been enough science now to show that if you’re not backing it up, you should not ever use hair. And the report says that you should not use microscopic hair analysis alone to claim a match...."
"There are inconsistent practices and inconsistent standards. Labs in one set of standards that are not followed by labs in another place.
"And one of the biggest problems that the forensic people pointed out to us in the committee is the too-close connections between law enforcement and the … forensic disciplines, and that was news to most of us.
"What they explained to us was in most instances, the labs are controlled by either the police chief, the prosecutor, law enforcement, so to speak. And the forensic people said it’s a mistake because there’s too much pressure put on the forensic people to deliver results and get them done quickly, and introduce the possibility of contextual bias for example. We’re trying to study that. …"
"Right, whatever the context is. You create the context. And now that examiner unknowingly is looking at the same print that he or she previously said [is a] 100 percent match, and in a significant percentage of those cases, they changed...."
