A criminal target—in this case, a sophisticated consumer of legal services—will typically want to retain a criminal lawyer whom he expects to be well-received by the prosecutor. Well-received, either because the chief prosecutor or her high ranking assistants know or at least know of the lawyer, and because he has a good reputation. Perhaps they're former colleagues. Or the defense lawyer is a former assistant to the chief prosecutor. It makes complete sense, right? That is, choose a lawyer whose call will be returned, whose meeting request will be honored and who generally has the respect of the office.
