Book author Tom Prior claims Brosnan told him Ronald Ryan had confessed guilt to shooting a prison guard. That's obviously a lie because as early as March 2003 Brosnan was interviewed on ABC National Radio when media journalist Kellie Day asked Brosnan about Ronald Ryan, who is is believed fired the fatal shot. Brosnan clearly replied; "I don't know whose bullet killed who." (Ref: http://www.abc.net.au/pm/content/2003/s817259.htm). In addition, to add support to Brosnan's comments was Bishop Greg O'Kelly. In February 2007, O'Kelly stated in the Catholic Archdiocese Southern Cross newsletter that Brosnan believed Ronald Ryan was innocent.
