When it comes to complex social problems, us sensible well-educated book-learnin’ types turn to the experts; we ‘believe science’ — unlike those snorting, hooting, semi-literate dunces. But over the next two weeks, we have two stories that will make you think twice about putting blind faith in experts. What if they don’t actually know what they’re talking about? That happens to be the case with many forensic experts. You know, the folks who work on blood spatter, ballistics, hand-writing analysis, fingerprints, etc. They aren’t Gods, they aren’t magicians, they ain’t anything like what you see on CSI. In fact, they get things terribly wrong; and when they do, the consequences can be catastrophic. We’ll reveal the crisis in forensic expertise, and look for ways to fix it.
