Barry Moredock was a private-practice defense attorney who specialized in cases where the defendant alleges their constitutional rights have been violated by their arrest. He also used to teach Constitutional law and once taught Alexandra Cabot, who would go on to become one of his most frequent adversaries as the Assistant District Attorney of Manhattan. Despite this, he was happy to see Cabot return from Witness Protection and offered her advice that caused her to return to her usual ways of dealing with crimes instead of the bloodthirsty method she briefly took.
