DNA "bungle" haunts German police

German police may have been hunting a non-existent woman for 15 years. Hmmm...and DNA is "infallible"? Identical female DNA found at 40 crime scenes. If they had had a DNA database of everybody, some poor cotton bud manufacturer might have gone down for a very long time. Of course not! the innocent have nothing to fear...except science abused in the name of law enforcement...
