As this article explains, fingerprints are by no means the foolproof form of ID we've been led to believe. All sorts of errors, both deliberate and accidental, occur. Almost as bad as DNA evidence or eyewitness testimony. Makes you wonder how many thousands of innocent men are locked up. http://www.boston.com/news/globe/editorial_opinion/oped/articles/2004/02/02/a_blow_to_the_credibility_of_fingerprint_evidence/

A more critical reading of the article, than that of the original poster, would indicate that perhaps two independent examiners be required for all fingerprint identifications or some other safeguards. The thread title makes you wonder how many sensible posters there are on Usenet message boards.

There are many old wive's tales still lingering in science. The idea that "no two snowflakes can be identical" has been questioned, and I believe disproven with samples to back it up. "Lightning never strikes twice" is definately false. I have a great deal of faith in DNA, but there are many questions. The idea that no two fingerprints could be identical is certainly a dubious result of early forensics. I dont think the question has be addressed formally in a satisfactory manner. I dont know if the question could really be answered - it's exceedingly complex even against today's science.

But remember, fingerprints have been shown over the years to be highly individual; nobody has found two people with identical fingerprints yet. So to get a false forensic match, you would need not only the incredible coincidence of two people with matching fingerprints, but also the added improbability of them both being in the same geographical area at the same time at a time when one commits a crime and the other doesn't have a solid alibi. So, multiply one in millions with one in millions and get a chance very, very statistically remote, assuming identical fingerprints exist but haven't been detected.

In our last episode, <vC1Ub.11471$F23.9530@newsread2.news.pas.earthlink.net>, the lovely and talented Bo Raxo broadcast on alt.true-crime:

Sorry, but false forensic matches have been shown to occur with disturbing frequency. The business of superimposing one finger print on another and having them line up completely is science fiction -- promoted by some really cheap-ass detective fiction. In fact, fingerprints are compared by people -- people who do not match the whole print, but only a few points of similarity. The number of points required for a "match" has never been examined scientifically. In many places there is no standard whatsoever and declaring a "match" is an entirely subjective process. That is not science; it's voodoo.
So, multiply one in millions with one in millions and get a chance very, very statistically remote, assuming identical fingerprints exist but haven't been detected.

And how do you define "identical fingerprints"? Do the finger print experts define it the same way? And remember to use the word "point" in your definition, if you are to be at all credible. -- "He that would exchange liberty for temporary safety deserves neither liberty nor safety.

You and Lars have both made an excellent point, I admit I wasn't thinking about how the match process works when blithely talking about "identical" prints. But I know they can run a print against a database. How does this match work? Is it pattern recognition software that examines the actual image for points of comparison? That's what I suspect. In which case the subjectivity of an examiner can be removed. OTOH, if it's a set of description points of some kind entered by an examiner, it is still completely subjective. Anybody know how, for example, the NCIC fingerprint database works?

My understanding is that they run points to get a "best match", but any parts that don't match later can be used to challenge the match. Sort of - it's enough to get you picked up, but if you can say "But I've got this scar that doesn't show on the crime scene prints.", then they're back to looking.

Yes, but whether two prints are considered a match or not is completely different from finding two fingerprints from two different people to be identical. Let's say I take a photograph of you. I can look at the photograph and say it's a match for your face. Now I start to blur the photograph. At some point, I can no longer say that it is a match for your face. Does that mean there is definately someone out there who has a face identical to yours? Of course not.
A more appropriate analogy would be if the government had a massive computer database of photographs of peoples' faces, taken with varying degrees of clarity, but of generally OK quality. Now we bring in a photograph of a specific individual, who may or may not be in the database. It may be of highly variable quality, and moreover may only show part of the face. Then the question becomes, will the computer match it to the correct individual, assuming he's in the database? If he's not in the database, what is the chance the computer will still find the next-nearest match, this time the wrong person? Lastly, even if the person is in the database, what is the chance the partial picture will be a closer match to someone other than the correct individual?

Provide a citation for this claim. Yes, but whether two prints are considered a match or not is completely different from finding two fingerprints from two different people to be identical.
We are in agreement. When I put same in quotation marks I meant a fingerprint expert going on the stand and saying that the prints are the "same". And in another state the same expert would say the prints are NOT the "same". -- "He that would exchange liberty for temporary safety deserves neither liberty nor safety.

Even an objective answer can be incorrect. Subjectivity is only one issue. Isaac
