All additional evidence of drug dealing/drug usage - LD, ERISP, evidence of DSC Mark Wakeham; mobile phone downloads; listening device material; telephone intercept material
- The objections to all of this evidence were on the basis of relevance and possible misuse of it by the jury (s 137).
- Detective Sergeant Mark Wakeham has provided an expert's report as to drug supply generally. He outlined his lengthy experience. No challenge was made to his expertise, only to the relevance of his evidence. His detailed statement covered the following topics: The nature of cannabis as a drug, how it is administered, that it is the most commonly used illegal drug in Australia, street level quantities, drug terminology and prices.
- At [13] of his statement he states:
"It is my experience the majority of drug dealers have a belief (to varying degrees) that law enforcement agencies actively monitor and record telephone conversations in an attempt to detect criminal behaviour. As a result many people involved in the supply of prohibited drugs when discussing drug transactions over the telephone, use a number of different strategies such as slang, predetermined codes or veiled speech in an endeavor to disguise the true purpose of their conversations. Many criminals believe that communicating in this way will prevent their conversations being used in evidence against them or at least inhibit an investigation into their criminal activities. The same holds true for SMS messages sent via mobile phones and messaging via social media applications."
- He then goes on to explain slang, jargon, veiled speech and codes.
- With respect to the case against both accused for murder, he states that he has examined certain transcripts and formed opinions about whether they disclose drug dealing.
