When you are comparing fingerprints taken at the scene of a crime to a standard print (sometimes called an "exemplar, , on CSI, anyway), the exemplar should be as perfect as possible. Comparing junk prints to other junk prints will yield a lot of false negatives (failures to compare) and/or "positives" that could be vulnerable to a clever defense lawyer.Liberty wrote:If we have been fingerprinted once, I don't understand why they need need the set taken years later to be so perfect. If they can get prints from a glass why do they reject so many as less than perfect? I never understood that.
IMHO. IANAL. IANALEO.
