The Acceptable Error Rate is ZERO

        If you are a Latent Print Examiner, you know the above statement to be true.  If you are an attorney, police administrator or other non-expert, this may sound unrealistically strict.  Scientists generally concur that a reliability of 95% constitutes scientific certainty
     
In many areas of science and many professions, such reliability serves society well.  For example, the acceptable error rate for Chicken Sexers (persons who examine the backsides of one-day-old chicks to sort males from females) is between 2.3 and 5 percent when examining 700 to 800 chicks per hour.
       
A latent fingerprint or palm print "identification" is the determination that two corresponding areas of friction skin impressions originated from the same person to the exclusion of all others.  This absolute identification decision can carry great weight in police decisions about investigations, and court decisions about guilt or innocence.  Latent Print Examiner errors involving evaluation (whether marks are of value or not) and elimination (marks were not made by a person) are serious, but do not normally carry the same potential for harm as erroneous identifications.  An example of the degree of importance afforded identification decisions can be seen in scoring procedures for friction ridge impression comparison tests.  Universally, even if an exam has hundreds of latent prints and thousands of record (inked) prints, some mistakes involving evaluation or elimination are expected, but a single erroneous identification is automatic failure.  The acceptable finger or palm print identification error rate is zero.
        Because in any field of human endeavor there will always be errors, quality control and quality assurance standards are necessary to protect society.  Standards for initial "training to competency," case by case quality control, and long term quality assurance including life cycle training and periodic proficiency testing are essential.  Periodic proficiency testing can reveal bad habits developed since initial training to competency.  It may also reveal deteriorating eyesight or other human deficiencies impacting casework.
 
        
One set of standards is set forth in the Quality Assurance Guidelines of the Scientific Working Group on Friction Ridge Analysis, Study and Technology (SWGFAST).
        Upon detecting an erroneous identification decisions (not just clerical errors and not just failing to find a "match")
most agencies immediately suspend the examiner from further casework activity.  Remedies to ensure a zero error rate include the following: Return of the examiners to friction ridge identification duties only after retraining and evaluation indicate the experts can operate at zero identification error rate; 
 Permanent transfer to other duties; Employment termination. SOURCE: onin.com-fp-problemidents.html#Zero_tolerance_explanation)

Interpreting Crime Scene Fingerprint Evidence

            This is a case where a woman convict was charged with participating in an attempted jailbreak. The allegation was based solely upon the discovery of a single fingerprint (the defendant's right, ring finger) which was found about three or four inches from the top of the bottom portion of a double-hung window in a second floor bathroom of the women's quarters of the County Jail in Barnstable, Massachusetts.
           The key to the crime scene and the defense case was the placement of that fingerprint and its orientation. In other words, where it was located and how it was situated on that pane of glass. I saw immediately that the way it was positioned on the window glass was not indicative of being transferred there as a result of an attempt to raise, or lower the window.
           The primary consideration in viewing a crime scene and examining the evidence should have been to learn and understand why, and how, the print got there. Clearly in order to attempt an escape the bottom portion of that window, it first had to be opened. There was no information that suggested the police thought anyone else had attempted to open it. Also, there was  no information, or evidence, that anyone else had touched that window on that occasion. When I examined and interpreted the scene, I considered that one most commonly
opens a double-hung window using either the heels of the palms, or the fingers and thumbs of both hands to exert upward force to raise the window. In this instance there were no palm prints, no thumb prints, no multiple prints. There was only that one, isolated, partial fingerprint on the window and it was parallel to the floor, parallel to the floor!
            Interpreting this crime scene was not at all complex, in fact as one fictional detective of old England would have said, it was "elementary". One could only speculate as to how that fingerprint came to be there, however, as I said before, had any print actually been transferred onto that window pane during an attempt to open the window, it would have to have been positioned differently. So, in order to conclude that this print was transferred to the window during an attempt to open it, that print would [logically] have to have been perpendicular to the floor, in a manner to create upward pressure to open the window. It's worth repeating because it is critical, the defendant's fingerprint was horizontal, parallel to the floor, thus not indicative of an upward leveraging action.
            To the credit of the Assistant District Attorney (Richard Piazza), once he learned of the defense EPA's interpretation of the crime scene evidence, he recognized that his own investigators had misread the "evidence." The case was dismissed. (Defense Attorney: Elizabeth Kliber, Hyannis, MA).

Disparities in Fingerprint Evidence

               In 2002, at Chicago, Illinois, a man was arrested and charged with selling cocaine to an undercover agent. The seized cocaine -- purportedly handled by the defendant,  was packaged in "brick" form, wrapped separately and further contained in a common white color, opaque, plastic trash bag. One aspect of the government's case was based primarily on a single fingerprint. To resolve that, his Attorney, Edward M. Genson, brought me in. To make a long story short, I literally saw one glaring disparity in this fingerprint immediately without a visual aid. The government alleged that the fingerprint they had developed was that of  the defendant's left, middle finger (#8). However, their experts failed to notice, or chose to ignore, one glaring disparity between the latent and inked impressions. There were two, in-line, ridge-endings, at the two o'clock position, three ridge-counts out from Chart Point (CP) #8. Ignoring those critical details obviated their identification. For those who have a compelling need to see for yourself, click on the EXHIBITS link, then Exhibit #11, on this site. The critical ridge endings can be found by locating the tip of the red arrow on the inked impression designated in CP8. From there, moving to the right and upward (at about 45°) counting three ridges out and you will find yourself right in the middle of a clear space between two opposing ridge-endings.
             The authenticity of the defendant's "Inked" print, acquired by the FBI, was not contended, but the ridge-endings found in that inked print were not to be found on the latent print exhibit. Courts and the experts agree that when comparing one fingerprint to another, the presence, or absence, of just a single attribute (in other words, just one disparity) precludes a conclusion of sameness. In this case, the absence of those ridge-endings from the inked fingerprint, standing alone, was sufficient to invalidate the FBI’S "identification." Having exposed the irreconcilable difference between the prints depicted on the chart panels, the defense examination and presentation of the fingerprint evidence was concluded. On June 29, 2005, one day after my entry into the case, AUSA POPE, himself, threw out the FBI’S fingerprint evidence from the government's case; game over.
