Fear, live in fear.
Fingerprints are not only fallible, there is plenty of objective evidence that false positives occur a majority of the time because the examiner heard something before examining the fingerprints, and that biased the examiner to make the evidence fit the theory.
And interesting example of what happens when your finger prints are in a data base is the unfortunate experience of Brandon Mayfield. Around three to four FBI fingerprint examiners were 100% positive that the fingerprints found in the Spain bombing were his. They were not, but it is highly probably that since the guy was a Muslim, and there were other factors, that these factors were the deciding issue, not the prints, because the identification process is in fact subjective. Fingerprint identification may be no more reliable than the witch hunting tests of yore.
Lets see, we burn witches because they are made from wood. And since wood floats, and ducks float, if you weigh less than a duck, you must be a Witch! (According to the Monty Python movie "The Holy Grail")
If your fingerprints on file, don’t be surprised if the Cops come knocking on your door because they found a fingerprint in Europe, and the fingerprint analyst decided you are the villain.
After all, you own guns? That makes you prone to violence, prone to extremist behavior, anti social, question authority, capable of independent thought and action. Bet you have books on guns, machine guns, war, etc.

This was an interesting listen on the reliability of finger prints. Not!
