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 NATIONAL INSTITUTE OF JUSTICE (N I J) COMMISSIONS SCIENTIFIC STUDY

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 validation of the basis for friction ridge individualization and standardization of comparison criteria:  

bullet

Basic research to determine the scientific validity of individuality in friction ridge examination based on measurement of features, quantification, and statistical analysis.  

bullet

Procedures for comparing friction ridge impressions that are standardized and validated.  

bullet

Basic research into the individuality of friction ridges requires objective measurement and statistical analysis.
