CSI effect: Juries increasingly demand lab evidence

ANCHORAGE, Alaska -- Police, frustrated by an uncooperative suspect, get a court order for his DNA. They throw on a pot of coffee, and, before the first cup is gone, the lab has results: a perfect match to the atom-sized sample collected at the crime scene.
