This seems to be because Gibson has bought the incredibly dubious DJ line
Gibson is purely a mouth for CASA, he doesn't have to think, he recites what he is told as the official CASA spokesman.
If he happens to overstep the mark, they can cut him loose and hire another mouth.
It is his managers (delegates), the board and perhaps the minister (not that the minister would ever consider in interfering with the day to day operation of CASA) that decide what he says
