      I remember seeing something on similar FBI files, which IIRC was over 5 years ago. They had bloodied palm and fingerprints left on a sheet. The problem wasn't so much a lack of evidence but that the pattern of the material intefered with the prints to an extent where a jury couldn't be expected to be able to identify it as a match. They used image processing to essentially subtract the patterning from an unstained area of the material to end up with a relatively clean image.

      It was a reasonably interesting e

    It never occurred to me that they COULDN'T do so. at least that's the way I always planned my crimes

      another assumption you should discard after learning the truth is the business of "fingerprint matching"

          Aha! Now we finally know who to blame for all those crime scenes where we didn't find any fingerprints.

        Mod parent up. I own the FBI Fingerprint training manual. It's not a real science. It's not quantifiable and is based on inductive reasoning.

        There is no data to support the alleged "uniqueness" of fingerprints other than "We checked, like, AT LEAST 100 people, and none of them were identical".

        They essentially place dots on distinctive features such as "curves" and "swirls" and then measure the distances between these dots. If a small fraction fall

          As well as being subjective there is also the issue of partial or distorted prints. It is rare to get a perfect print like they do on CSI.

          DNA matching is also not all it's cracked up to be either. Again there are issues with poor samples and the practice of "amplifying" to obtain a usable amount of material. Even with a good sample matching is not 1:1, you only get a probability. At best most real world tests are only accurate to about 1 in 10,000 at best, pretty crappy odds.

    A clever technique involving lasers and polarised light to detect fingerprints on clothing was used in 1985 in New Zealand to catch the murderers of an environmental activist.

      There's probably not a lot on the net due to how long abo it was but here's one thing in L-space:
