57 The belief which the undercover operators sought to inculcate in Darren Lauchlan was a sense of allegiance, trust and reliability among members of the crew and hence the frequent repetition of the theme of trust, loyalty and honesty between members. It is nevertheless a possibility that simply by implication from the activities in which the undercover police operatives pretended to be engaged, namely, protection rackets, stand-over recovery of money from "Sue", a jewel robbery, the distribution of weapons including sub-machine guns, and the magnitude of the criminality involved in a major drug importation, that Lauchlan may have inferred that the members of the gang would not hesitate to be ruthless if occasion demanded, if they were so disposed or if they felt threatened and that the ruthlessness might include violence. However much the police undercover operatives attempted to dispel this possibility, it is difficult to escape the conclusion that the entire setting and the magnitude of the criminality involved meant that some kind of implicit background danger was inevitable and that, indeed, protestations of freedom and ability to withdraw might themselves give grounds for suspicion. This notwithstanding, the evidence presented about the acting out of the various scenarios, in the detail in which it was given, including, in particular, the videotape of the final interview at Crown Towers Hotel on 18 December 2003, does not suggest that Lauchlan at any time felt threatened or harboured any fears for himself, Lynda Hammond or their children. He came voluntarily from Tasmania to Melbourne on several occasions and returned alone. No force or threats were made to induce him, Lynda Hammond and the children to come to Melbourne and stay at the flat at St Kilda. He had never expressed any fears or dissatisfaction. His entire demeanour during the critical interview of 18 December 2003 was that of a person who was relaxed and speaking freely.
