Bill Oakley is a deputy district attorney.
Jimmy continuously attempts to plead with Bill to let off his client. Bill responds with the phrase "petty with a prior" each time he asks. They eventually come to an agreement when Jimmy makes a deal to get a continued sentence for his client and in return, if the client stays clean, Bill can file him for dismissal in six months. ("")
Jimmy comes to Bill once again for a deal for his client. Bill declines all of Jimmy's offers, telling him that his client drove drunk into a shopping center and killed three civilians. Jimmy corrects him and tells him that he is thinking of the wrong client. His client was only charged with armed robbery at a liquor store. The two then make a deal to let the client off in ninety days with good behavior. ("")
While Jimmy is booked, photographed and fingerprinted, Bill shows up to gloat at his misfortune. "How the mighty have fallen" he laughs. He does, however, take pity and says he will see if he can push Jimmy's first appearance up. ("")
Bill prosecutes David Estrada, a youth accused of throwing a cinder block through a grocery store. Kim Wexler, serving as the youth's defense, demands the sentence be reduced to a few months probation, which Bill refuses to cooperate on. He is convinced to allow this when she threatens to reveal that the youth was not mirandized prior to his confession. ("")
