New evidence produced through post-conviction DNA testing has led to over 200 exonerations nationwide, and has cast a spotlight on the flaws in eyewitness testimony and visual memory that lead to wrongful conviction.
Not everyone sees DNA evidence as concrete proof of innocence, however. John Fairgrieve, the Clark County prosecutor on the Davis-Northrup case, cautions against viewing DNA evidence as an “ironclad alibi.” Sometimes, he argues, an individual can have knowledge about a crime that constitutes strong evidence, even if it can’t be tested in a lab. “Reliable evidence,” says Fairgrieve, “comes in many different forms.”
