SUFFICIENCY FOR CONCLUSIONS The scientific measure of sufficiency for individualization of friction ridge impressions is not a strict number of Galton characters in agreement, nor a belief in the transference of biological uniqueness of level 3 detail. Sufficiency is the amount of detail present in each unknown impression, and how this amount of detail compares to the closest non-match ever found with concurrent equal levels of detail.
With issuance of the 1973 IAI resolution which stated, "That no valid basis exists at this time for requiring that a pre-determined number......", the standardization committee strongly recommended a federally funded study of fingerprints. Twenty-seven years later a solicitation for such a study was issued. The grant funding for this solicitation was recalled and the solicitation was rewritten to include all pattern evidence sciences. This does not infer that friction ridge individualization validation is not needed. The
National Institute of Justice (NIJ) has identified the need for
