Please watch this video from 58:10 as the PT officers empty one box of clothes with no separation between those clothes at all, meaning that cross-contamination would be almost inevitable. If one item had cadaver scent on it then those rubbing against it in that box would likely as not be contaminated. That is why in this country no police force would collect evidence in such a slapdash way. They would ensure that each item was separately bagged.

I had long been aware of the potential of cross-contamination in these clothing boxes because of the slapdash handling of the clothes but and this is a big but, I hadn't actually noticed exactly what follows from 1:01:00 to 1:01:25 with that in mind. The three clothing alerts are almost adjacent to each other. And having seen how the PJ officers took the clothing earlier in the film from another box the fact that these three items are so close suggest very strongly that they could in fact have been pressed against each other in the cardboard box. No lawyer would fail to challenge the notion that these could be recorded as three separate alerts when such a strong possibility of cross contamination exists. It is almost impossible to believe in such a situation that cross-contamination would not occur.
Would it be accurate to describe this as three separate alerts? Personally, having seen that video, I think not.
But why does this matter? Surely the alert is to cadaver scent?
Well yes, but it means that only one of those articles may have been directly in contact with a cadaver in the past which markedly reduces the necessary contact with any cadaver.
Going beyond the clothing alerts to Cuddle Cat.
Could there be any possibility of cross-contamination between the clothing and the toy during the months between the disappearance and the introduction of the dogs? Well yes, there could.
There are lots of pictures showing the cat against various articles of clothing including the trousers which were alerted to in the gym.
Any lawyer in court would be utterly remiss if they failed to indicate this potential for cross-contamination and the way in which such cross-contamination would reflect on the potential number of actual contacts with cadaver scent.
Just from this short post it is clear that there are legitimate questions as to whether we can reliably determine the number of necessary contacts with any cadaver from the dog alerts.
Much more to come but I have to be elsewhere now till late this evening.
