The Project is never to be trusted.
I am reliably told the video in question was part of a pool arrangement in which Channels 9,7 and 10 all had the same footage.
Channels 9 and 7 ran the video in full and in context.
Only Peter van Onselen's devious Channel 10 edited the truth to make his nemesis the Prime Minister look bad.
Blaming the audio is bullshit.
