And Lord Holder will appoint the prosecutor...and the victims will be us...
A special prosecutor generally is a lawyer from outside the government appointed by an attorney general or, in the United States, by Congress to investigate a government official for misconduct while in office. A reasoning for such an appointment is that the governmental branch or agency may have political connections to those it might be asked to investigate. Inherently, this creates a conflict of interest and a solution is to have someone from outside the department lead the investigation.
