Yes Krusty and his fibbing ways worked. Have a look in the media or on public commentary and its those "average" hours that get quoted time and time again. He's a clever fellow indeed and our system just isn't accurate or resourceful enough to pick up that he is actually lying at a Senate Inquiry.
Its up to the Senators to say "right, hand over every single record and lets get a forensic analysis done". Its also up to the union to pursue Mr Buckkanan in the courts if he has been lying in a Senate Inquiry. I'd hope their lawyers are pouring over every word.
The aim is to mislead the Senators and influence public opinion much like 89 or with the wharfies.
