It takes determined leaders to subject vital state agencies to independent scrutiny even after a full-scale internal investigation of any wrongdoings that surface.
But so paramount is the safeguarding of public trust in the Home Team that the Government is to ensure it has the benefit of a detached assessment of how robust, fair and thorough the system is when internal probes are conducted.
It is not as though there is any reason to think that such self-examination is less than objective but there is a clear need to avoid all doubt following a series of events. High-profile senior officers were charged with misconduct in 2012, the Immigration and Checkpoints
