"Having examined the videotapes of the officers counting the banknotes on unprotected table tops I would suggest that Ms Hynes' proposition 'that the outermost notes in a bundle might become contaminated to a higher degree due to more handling and closer contact with the surface' may be incorrect. The video tapes clearly show the officers tapping bundles of notes edgewise onto the surface in order to make the neat bundles. Handling and tapping bundles of notes onto a surface in this way could easily result in traces of drugs present on a surface being transferred, more or less evenly, to every single note in a bundle. "
"When considering each defendant's case, if you think the explanations that I have just summarised amount to a reason why you should not hold that defendant's failure to explain the contamination in interview against him, do not do so. Further, each defendant has told you that he was advised not to answer the questions put. You should consider whether or not that defendant is able to decide for himself what he should do or having asked for a solicitor to advise him, he would not challenge that advice. On the other hand, if it does not, in your judgement, provide an adequate explanation and you are sure that the real reason for that defendant's failure to account for the presence of the heroin contamination on those notes was that he then had no innocent explanation to offer in relation to this aspect of the case, you may hold that failure against him."
