The size of the dataset sets the maximum odds of a false positive. We are seeing false positive problems with DNA and the FBI won't cooperate into investigating. (The problem comes from relatives--while two random people are astronomically unlikely to false positive close relatives are likely to have many matches anyway, the odds of a false positive are merely low, not astronomical.)
