CIA auditor being investigated by CIA

John helgerson, who headed an aggressive investigation into the CIA's detention tactics, is being investigated by his own agency:

The director of the Central Intelligence Agency, Gen. Michael V. Hayden ,has ordered an unusual internal inquiry into the work of the agency’sinspector general, whose aggressive investigations of the C.I.A.’sdetention and interrogation programs and other matters have createdresentment among agency operatives.       

A small team workingfor General Hayden is looking into the conduct of the agency’s watchdogoffice, which is led by Inspector General John L. Helgerson. Currentand former government officials said the review had caused anxiety andanger in Mr. Helgerson’s office and aroused concern on Capitol Hillthat it posed a conflict of interest.

So much for legitimate internal watchdogs.
