On being scientific and having environmental factors in contamination, the whole idea of cocaine being on notes has been around for a long time. It has been found on toilets and in suitcases. If my brother used a suitcase last week and he had cocaine in it and I take it the next week and there is no cocaine in it, it will show up if there has been contamination. That is human. We deal in notes. We deal in suitcases and all these things. The dogs are not going into the local shop with the fiver that has been used to snort cocaine to buy something with it-----
