Courtroom Methodology: Cross-examination Vulnerable Areas of Fingerprint Testimony Age of the Latent Print Source of the Latent Print Transcripts of Prior Testimony Use of Books and Articles in Cross-examination Tactics of Defense Attorneys Completion of Testimony Conclusion Glossary of Commonly Used Courtroom Terms References Appendix Daubert Hearings, reviewed by Mr. Edward R. German The fingerprint expert is unique among forensic specialists. Because fingerprint science is objective and exact, conclusions reached by fingerprint experts are absolute and final. Acceptance of fingerprint experts did not spontaneously evolve; it was scientifically and painstakingly developed over the past 80 years through the diligent efforts of innumerable identification officers. They established a heritage of exactness in their fingerprint identifications that is now routinely accepted and relied upon in courts of law. The professional status of the fingerprint expert is well earned and demands preservation. It is a standard of excellence by which all who participate in the scientific area of fingerprint identification are judged. It is the authors’ hope that by studying this chapter, identification officers will further enhance their expertise as expert fingerprint witnesses and thereby stand ready to perform this vital service while at the same time maintaining and enhancing this priceless heritage. A discussion of a recent (July 1999) hearing in a case (U.S. v. Byron C. Mitchell, U.S. District Court for the Eastern District of Pennsylvania) that raised the issue of fingerprint individuality in a Daubert context can be found in the Appendix to this chapter. Definition of an Expert An expert is generally defined as any person who is skilled in a specific science, trade, or occupation. Because of this particular knowledge, the expert is qualified to analyze or compare a stated set of facts and render an opinion based upon those facts. This opinion is permitted because of the expert’s special knowledge, which the layperson generally does not possess.
