Peta Credlin showed her mettle at Andrews press briefing today, page-4

Credlin has been on to this fiasco for a few weeks. She has done quite a few incisive commentaries on her nightly show. Whether you like her politics or not, she is prodigiously intelligent and seems to have a firmer grasp on the facts of the inquiry than either the Judge ( who us at grave risk of sullying her reputation by her ramshackle handling of the inquiry) and Counsel assisting ( who you can only assume is on a promise of a leg up to the Judiciary, given the poor questioning)

Credlin is the one who dissected the time lines, came up with the missing 6 minutes, and provided the impetus for the Opposition to urge the Board to re-open the inquiry. Credlin also is the one who recommended calling the Premiers chief of staff - who astonishingly was not called by the incompetent Counsel assisting. She is also the one who chided the Board for not summoning all phone records, including incoming calls.

The evidence points to an almost irresistible conclusion that during the missing 6 minutes, the Police Commissioner received a call from Andrew's chief of staff instructing him that private security would be used. Those instructions can only have come from one person. A person who has clearly perjured himself under oath and lied to the public.
