Title: Some Aspects of Our Work on the NRC Bullet Committee
Author(s): Clifford Spiegelman*+ and Karen Kafadar

Address: 447 Blocker -3143, College Station, TX, 77843,
Keywords: scientific method ; hypothesis ; sampling ; evidence ; FBI ; NRC
Abstract:

In this talk, we discuss and expand upon important recommendations from the NRC Committee on Scientific Assessment of Bullet Lead Elemental Composition Comparison. This includes an expanded discussion on the role the scientific method can play in improving the credibility of FBI Crime Lab conclusions. We will suggest that the greatest contribution of the statistical community may be in encouraging scientific laboratories to better comply with the accepted norms of scientific practice. We also will emphasize technical aspects of the NRC report, such as hypothesis testing in a multiple comparison framework and the need for a greatly improved sampling plan to improve the credibility of Crime Lab conclusions.
