been searched for bombs and that searching bins is normally a high priority, and is specified in New South Wales police permanent circular 135. Army dog handler Keith Burley said that his dogs could smell very small quantities of explosives, and were expected to be used for the event. Burley said they were unexpectedly called off a few days prior without explanation. The entire truck and all bomb fragments were dumped immediately afterwards at an unrecorded location. This prevented forensic evidence, such as the type of explosive used, from being gathered. (Hatton compared that to the detailed evidence retrieved from the Pan Am Flight 103 that exploded at 30,000 feet.) In 1983, William Reeve-Parker provided a statutory declaration that an army officer had admitted planting the bomb by switching rubbish bins 24 hours earlier. Reeve-Parker denied knowledge of who the officer was, although he "had helped his son". Reeve-Parker was never called as a witness at the coronial inquest. The officer-in-charge of police immediately after the bombing, Inspector Ian MacDonald, claimed there had been a cover-up. In 1995, Andrew Tink said that it had been alleged former Attorney General of New South Wales Frank Walker and Federal Government Senator Gareth Evans had been told by a CSIRO scientist that under pressure from ASIO they had made two fake bombs in the week prior to the bombing. The bombs were designed not to explode but could do so in a garbage truck compactor. The principal private secretary of a federal senator was told that the bomb squad was waiting nearby at this early hour of the morning. Barry Hall QC said that this would make it hard to claim that they were not involved. The government would not permit people from the bomb squad to be called as witnesses to the inquest. Sgt Horton stated that he saw an occurrence pad entry that showed the warning call was received at 12:32, 8 minutes before the bomb exploded. It was not relayed instantly to the police out front. At the inquest four other versions of this pad were shown, each timing the call at 12:40. Many of these issues were identified by Terry Griffiths, a former policeman who was seriously injured in the bombing, who had called for an inquiry. Peter Collins, NSW Attorney General 1991–1992, said "The Hilton Bombing is a history of half truths, a litany of lies". Barry Hall
