"If I could hand you a further document. (Handed to witness:). What is that document that I have just handed to you?---That is an Australian Federal Police protected minute addressed to Detective Senior Sergeant Maher from senior liaison officer Shane Castles from Los Angeles, dated 11 June, 1997. If you could turn to the last page. Was that faxed on 12 June of 1997?
---It was faxed from Canberra on the 12th June 1997. What is your understanding of that letter?---Basically sets out from the United States that they were notified by Detective Senior Inspector Rod Collins from the office Homicide Squad that request they proceed with the covert collection of DNA samples from Bui Quang Thuan in the absence of his brother. It gives 3 options that Shane Castles presents as possible ways to obtain the samples from the suspect. All right. If you could just briefly describe what each of the options was?---One was to anticipate the suspect will return to his home in San Francisco at the conclusion of summer school in July and proceed with voluntarily attendance at the Emeryville police station and provide a statement. A second option was within the next four weeks in which the services of a local Police Department in (indistinct) Long Beach devise another scenario for the covert collection of DNA samples in line with the present circumstances and proceed accordingly. And number 3 which was the preferred option, was to continue with the current plan which will involve the travel of both an Emeryville PD and Oakland PD officer to Los Angeles with as soon as possible interview the suspect regarding a card club incident and achieve the other result. Why do you say the option 3 was the preferred option?---Because they had a legitimate reason to interview him and I believe that that was the option that was - was most appropriate in terms of resources, time and it was a legal way to obtain samples. And was that the option recommended by Shane Castles?---Yes, it was." "Okay. All right. So option 3 was carried out. Could you advise the court how option 3 was carried out, what was done in relation to collecting the samples?---Well, as discussed in that, the previous minute, an officer from the Oakland Police Department by the name of Zbigniew Hojlo travelled to Los Angeles with another policeman from Emeryville Police Department by the name of Frank Sierras, they met with the suspect at Long Beach college where he was studying and they spoke to him in an interview room or a room that was allocated by the security staff there at the college and they had an interview with him in relation to his involvement into a matter in the San Francisco area and he was permitted to smoke during that interview, and at the conclusion of that interview the cigarette butts were photographed in situ and then collected and labelled and several days later one of the police officers travelled to Australia with those cigarette butts." "Did you at any stage contemplate using the forensic evidence provisions of the Victoria Evidence Act?---Yes, we did. Was the result of those contemplations?---All my inquiries in relation to the forensic procedures legislation led me to the office of Public Prosecutions, the Federal Attorney General's Department, and the relevant authorities in the United States and I was told that they didn't apply. Were there any other options for obtaining the sample of DNA from Bui Quang Thuan considered?---Yes, we considered obtaining a court order. Court order from where?---From the United States. And to do that we would require a mutual legal assistance treaty between the Australian government and United States government which would take time. And the other problem with that would alert the suspect as to his interest by the Australian law enforcement bodies. When determining the best method by which to obtain the DNA samples from Bui Quang Thuan, what were your primary concerns?
---Primary concerns were to the admissibility of the evidence in the United States and in this court, Victoria, and also to ensure that they obtained so virtually not to alert the suspect. Did you at any stage regard the method ultimately used to obtain the DNA samples from Bui Quang Thuan as being improper or illegal?---No." "Had either of the Buis been in the jurisdiction, what procedure would you have followed?---I would have followed the local legislation in Victoria as I did with Le Than Long." "Very well. At all times it was proposed to use this evidence on the trial of Bui Quang Thuan if he was brought back?---Yes. Did you have in mind if he was brought back, to make a formal request of the type that you made to Mr Long?---That is what we intended to do."
