How did Captain Peter Bosco learn about his reassignment to Headquarters?

 Was there a rush to judgment?  Was Scoppetta so eager to have a newsconference to show the world that he was taking action that he acted before he had all of the evidence?

Captain Peter Bosco learned of his reassignement from the radio while he was driving his car.  Scoppetta in his eagerness to show the world that he was doing something did not have the common courtesy to make sure that Captain Peter Bosco was personally told of his reassignment.
