Child witnesses and the confrontation clause

InMaryland v. Craig, the United States Supreme Court relied heavily on a brief prepared by a committee of the American Psychology-Law Society on behalf of the American Psychological Association (APA). The APA brief concluded that sexually abused children may be particularly vulnerable to distress in the legal process, especially when forced to confront the defendant face to face, and that such acute distress may be inconsistent with the state's interests in promotion of reliable testimony and child welfare. APA also argued that psychological theory and research provide foundations for individualized determination of the need for measures to protect children from face-to-face confrontation. *** DIRECT SUPPORT *** AFE06051 00002

Metabolite sensitivity in the methaqualone radioimmunoassay.

Recent literature reflects the increased use of RIA as a qualitative and quantitative tool. This study exemplifies the problems that may arise when this technique is used for quantitation. Caution must be exercised, and a physiological and toxicological understanding of each particular drug is essential to provide credible results. It is evident that the sensitivity and ease of the RIA method for methaqualone makes it invaluable as a screening test, but confirmation and quantitation of this drug must remain with those methods that can quantitate each metabolite.
