THE LAW ABOUT THE REST OF
FORENSIC SCIENCE
Michael J. Saks*

I.  INTRODUCTION
The most important legacy of DNA fingerprinting and the de-
bate surrounding it will likely be a spillover of standards of empirical
testing and statistical rigor to many other forensic sciences which,
somehow, have exempted themselves from the conventional standards
of scientific rigor. I In short, the debate over DNA fingerprinting may
compel the rest of forensic science to become more recognizably
scientific.2
After a bumpy start, the debate over DNA typing has proceeded
with unusual thoughtfulness. The earliest American cases admitting
genetic identification evidence did So on the strength of a few expert
witnesses whose testimony was received with little or no challenge.'

I For discussions and evidence bearing on the point that appropriate scientific standards
have not been applied in other forensic sciences, see, A. MOENSSENS, F. INBAU & J. STARRS,
SCIENTIFIC EVIDENCE IN CRIMINAL CASES 6-9 (3d ed. 1986); J. PETERSON, E. FABRICANT,
K. FIELD & J. THORNTON, CRIME LABORATORY PROFICIENCY TESTING RESEARCH PRO-
GRAM, (1977); Risinger, Denbeaux & Saks, Exorcism of Ignorance as a Proxy for Rational
Knowledge: The Lessons of Handwriting Identification Expertise, 137 U. PA. L. REv. 731
(1989); Symposium of Science and the Rules of Evidence, 99 F.R.D. 188 (1983). The paucity of
empirical research concerning the accuracy of the underlying assumptions of many of the most
familiar forensic sciences is immediately evident to anyone who tries to search for such
literature.
2 The authors wish to thank Professor Paul C. Giannelli, who is the Albert J.
Weatherhead III & Richard W. Weatherhead Professor of Law at Case Western Reserve Uni-
versity Law School, for first sharing the prediction that the DNA debate may make the other
forensic sciences more recognizably scientific.
