What are the false positive and false negative rates of DNA testing? Paternity tests for example seem to have ~1.1% false positive rates, and that’s comparing a single sample to a single other sample.<p>Keep in mind that comparing a DNA sample to a gallery for the purpose of large-scale matching raises the false positive likelihood significantly. I’m not at all convinced that this could be done without convicting innocent people.
Given the overload on crime labs, the probability that these things have contamination is near 100%.<p>I should be happy about this as it will accelerate the change to "DNA is useless without corroboration". Unfortunately, too many poor people will wind up convicted based on this kind of useless evidence before someone rich comes along with expensive enough lawyers to put a stake through it's heart.
