>that while latent fingerprint examiners can successfully rule out most of the population from being the source of a latent fingerprint based on observed features, insufficient data exist to determine how fingerprint features really are unique

While it doesn't narrow it down to a *single person, Fingerprints are still evidence. The litmus is to convince a jury of your peers.
