The author, a bioethicist, describes his experience when he was asked to testify as an expert witness for the prosecution at the January 1991 trial of Dr. Jack Kevorkian. Caplan only agreed to testify with great reluctance as he does not believe that there necessarily is a place for bioethicists at legal trials. His main concern is that the presence of a bioethicist could suggest that one side or the other has “ethics” on their side, thus distorting the fairness of the legal process. (MM)
