Fingerprints

Think fingerprints are objective, reliable and unaffected by human judgement?  Think again. 

“We took fingerprints AI-fpandpencil-cropthat have previously been examined and assessed by latent print experts to make positive identification of suspects. Then we presented these same fingerprints again, to the same experts, but gave a context that suggested that they were a no-match, and hence the suspects could not be identified. Within this new context, most of the fingerprint experts made different judgements, thus contradicting their own previous identification decisions. Cognitive aspects involved in biometric identification can explain why experts are vulnerable to make erroneous identifications.”[1]

We provide a range of fingerprint services including case review

A defence fingerprint review involves an independent forensic expert evaluates the fingerprint evidence presented by the prosecution in a criminal case. The purpose is to ensure the evidence is fair, unbiased, accurate, and reliable.

It should be remembered that, despite public perception, a fingerprint analysis is an opinion, not an irrefutable fact. 

We have already provided statements in other fingerprint cases over the last few years where we challenge the basis of the certainty expressed in fingerprint evidence. For example,

" It is not argued herein that fingermarks cannot provide evidence, but that there is no reliable basis for opinions of certainty, and that the fingerprint officer uses an inappropriate means of presenting the findings inasmuch as not providing any reliable guidance as to the probability that the defendant did leave the mark..."

The Fingerprint Inquiry, in conjunction with the finding of the Appeal Court in R v Smith, now provides further support for such challenges to fingerprint evidence.
