* Latent fingerprints- obtained by using fingerprint powder to make the latent print visible.

These lift cards are examined by fingerprint identification experts who compare the friction ridge detail in the known print.

| + | Even if one assumes that it is true that no two people in the world have the same fingerprint, this argument is logically flawed when it comes to the identification of latent fingerprint fragments. It simply does not follow from this that a fingerprint examiner can reliably make an identification from a small distorted fingerprint fragment that might reveal only a small number of ridge characteristics. | ||

| + | The current legal debate of fingerprint identification evidence is NOT the physiology of fingerprints, i.e the uniqueness of the mark. The issue is whether fingerprint examiners can accurately and conclusively determine the identity of an incriminating latent print found at a crime scene. This is because fingerprint experts must rely on the naked eye to reach a conclusion. This is clearly very problematic and it reinforces the argument that fingerprint identification evidence can be unreliable. | ||
