"The speakers were all very knowledgeable about DNA testing and how it would be presented in a courtroom. They all had extensive courtroom experience which made their seminar presentations very meaningful to counsel, and were well aware of the challenges DNA testimony would create to a jury. They offered suggestions and anecdotes about how to convey the underlying science, not only to jurors but also to counsel. The seminar was very much a valuable learning experience. "
