CASA have been put under the microscope by this inquiry and have been found wanting. I can not imagine anyone being foolish enough to allow them to go free, but if they do, CASA's failings will be thrown into stark relief when they inevitably manifest themselves into an accident-and they know it.
I would not give up on the inquiry just yet, it is not every day that a group of Senators has potentially hundreds of lives in his or her hands. I think the good Senators are aware of the consequences of getting this one wrong.
