Students and practitioners of criminal law will recognize our contributors as the co-authors of Scientific Evidence (1986), perhaps the leading work in its field; as occasional contributors to the Bulletin in the past; and as leading authorities in the area of scientific evidence. Advances in the laboratory have led to pressure on the criminal justice system to utilize scientific techniques in the development of a case. Firearms identification, DNA testing, blood grouping tests, AIDS tests, drug tests, and a host of other areas raise serious concerns for the prosecutor and for defense counsel. Both should find answers in the work of these authors. 27 footnotes (Publisher abstract)
