The shooting of university student Jason Miles at a political rally hosted by controversial speaker Judith Barlow leaves any number of suspects, but after Green and Cassady prove that two of the people they've questioned are lying about their alibis, they turn their attention to Malcom Yates, an older PhD student who creates human embryos to harvest stem cells. It is discovered that Yates has Parkinson's disease and finds Barlow's tactics as a direct threat to his job and life. Yates' attorney, Bernie Adler, is from the ACLU, during the trial Silver infuriates the jury by calling everyone racial epithets, which angers the judge.
