A Note for FBI NGI Users...
One of the most valuable pieces of fingerprint-related information shared at the 2018 IAI Conference involves FBI Lab and CJIS research about about NGI latent print search result candidate scores. At the IAI Conference in San Antonio, FBI Latent Print Examiner Kyle Tom explained that preliminary research showed that when the matching scores of the #1 and #2 candidates have a difference of 1,250 or more, 83.5% of the time it will be an identification.
  
This is important because it means all agencies should consider implementing a policy that any such 1,250 or more difference in NGI candidate responses should require review by more than one examiner - either because the first examiner made an identification, or because there is an increased chance of an erroneous exclusion. Hopefully, the FBI will publish research on this topic in the future.
  
Some agencies are of the opinion that allowing examiners to see the matching scores in candidate lists biases them and should be precluded. The current chair of the OSAC Friction Ridge Subcommittee AFIS Best Practices Task Group (Mike French) and I are both of the opinion that AFIS matching scores are an important objective measurement which can lend valuable information to the examination process and aid quality assurance.

IAI Latent Print Certification Board Update- 2018
by Stephanie Howard, CLPE
Ontario Provincial Police
LPCB Chair
 
Presented at the International Association for Identification Annual Educational Conference during 29 July - 3 August 2018 in San Antonio, Texas, USA
   
This excellent presentation updates activities of the LPCB during the past year, including details about test impressions which caused decertification of examiners (8% failure rate).

Discussion after the presentation included recommendations by many CLPEs present to cease decertification due to one missed ident (in the same manner that not identifying all impressions during initial certification testing is not a failure). The LPCB explained they will take the recommendations received during the meeting (and all other communications) under consideration.

Small Agency Latent Print AFIS Capabilities in 2018
by Ron Smith, CLPE and Ed German, CLPE
 
Presented at the International Association for Identification Annual Educational Conference during 29 July - 3 August 2018 in San Antonio, Texas, USA
   
Hundreds of latent print examiners at small agencies in America are unable to search unsolved case latent prints in the FBI's national database. In the nation's fifth largest state (Illinois), very few local agency latent print examiners can search latent prints at the FBI... meaning months or years of turn-around time before examination begins on evidence they submit to Illinois' overworked (and under-financed) state crime labs.

Additionally, more than half of latent print examiners surveyed who have current access through state or regional networks desire to be able to submit latent prints directly to the FBI via email (an avenue which was shut-off about three years ago for most agencies to even explore ).

Some believe the major AFIS vendors are pushing back against agencies being able to directly search the FBI without buying $30K to $50K terminals to route through the same AFIS vendor's state systems. Other experts see push-back from state law enforcement to allow local agencies to circumvent their networks (electronic or crime lab snail-mail) even though directly searching the FBI would often solve investigations faster and overall reduce criminal activity in the impacted jurisdictions.

New Paradigm for Fingerprint
Reporting Without Individualization
by Henry Swofford, Chief Latent Print Unit
US Army Criminal Investigation Laboratory
Presented during a Forensic Technology Center of Excellence webinar on 14 July 2016

In November 2015, the Defense Forensic Science Center (DFSC) issued an Information Paper announcing the decision to cease using the terms “individualization” and “identification” in latent print technical reports and expert witness testimony. This presentation explained the reasoning behind the new reporting language of the DFSC. 

For over 100 years, fingerprint evidence has been used as a valuable tool for the criminal justice system.  Relying on the generalized premise of “uniqueness”, the forensic community has regarded fingerprint evidence as nearly infallible having the capacity to “individualize” the source of a fingerprint impression to a single individual.  While the uniqueness of a complete record of friction ridge skin detail is generally undisputed, the extension of that premise to partial and degraded impressions has become a central issue of debate.  Nevertheless, forensic science laboratories routinely use the terms “individualization” and “identification” in technical reports and expert witness testimony to express an association of a partial impression to a specific known source. 
 
Over the last several years, there has been growing criticism among the scientific and legal communities regarding the use of such terms to express source associations which rely on expert interpretation.  The crux of the criticism is that these terms imply absolute certainty and infallibility to the fact-finder which has not been demonstrated by available scientific data.  As a result, several authoritative scientific organizations have recommended forensic science laboratories not to report or testify, directly or by implication, to a source attribution to the exclusion of all others in the world or to assert 100% infallibility and state conclusions in absolute terms when dealing with population issues.  Consequently, the traditional paradigm of reporting latent fingerprint conclusions with an implication of absolute certainty to a single source has been challenged.  The underlying basis for the challenge pertains to the logic applied during the interpretation of the evidence and the framework by which that evidence is articulated.  By recognizing the subtle, yet non-trivial differences in the logic, the fingerprint community may consider an alternative framework to report fingerprint evidence to ensure the certainties are not over or understated.

NIST Seeking Fingerprint Examiners for Facial Identification Study 
 
Dear Colleague,

One of the key questions in forensics is measuring the accuracy of facial forensic examiners.  To address this question, we are conducting the Measuring the accuracy of facial forensics comparisons research study.  This research study will measure the performance of facial forensic examiners using the tools and methods in their laboratory. We are recruiting facial forensic examiners to compare the faces in 20 image-pairs and answer a background survey. 
 
We are also recruiting non-examiner face experts and fingerprint examiners to take the same study.  Non-examiner face experts are familiar with faces but have not been trained in facial forensic comparisons. We are looking for fingerprint examiners who do not have experience in facial comparisons.  Fingerprint examiners have been trained forensic comparison but do not have experience with faces.  These two groups will allow for a detailed analysis of the accuracy of facial forensics comparisons. 
 
By participating in this research study, you will assist in developing a scientific measure of performance of facial forensic comparison.  These results may help meet the Daubert standard for the admissibility of expert witness testimony.
 
By volunteering for this research study, you may request your accuracy at comparing the extremely challenging faces in this study. If you are willing to volunteer, please contact the principle investigator, Dr. Jonathon Phillips, by email at jonathon.phillips@nist.gov or by phone at +1 301-975-5348.
