Amaral and the dogs

[John]

I will explain this as simply and clearly as I can.

Cadaver dogs alert to blood

Blood dogs alert to blood.

So where a blood dog alerts, there is blood.

And if a cadaver dog alerts in the same place, the cadaver dog, also, will be alerting to blood.

Not necessarily, the cadaver dog could be alerting to blood or cadaver or both as Carew has already pointed out.  See my reference to 3 dogs.

[John]

A small point is that there was no forensic evidence that there was any blood anywhere in 5A or in the car. We're all assuming that the trace DNA must have been blood because that's all that Keela was trained for.

If a dog is trained to react to blood and subsequently does so then it is a fair bet that blood has been found.

By the same token, if a dog is trained to react to both blood and cadaver and subsequently reacts then the only conclusion which can be drawn is that the substance found was blood, cadaver or even both.

Pare the statement right down.

If there is blood in one spot inspected by both dogs, both dogs will react to blood.

All else is conditional.

I don't agree.  Unless you apply the 3-dog test, nothing can be guaranteed.

You think that if there is blood present, one dog or other might miss the scent?

[Brietta]

If you watch the first alert in the Rua Das Flores house video, it is not to the cat, it is to the last thing sniffed, which answers both your questions.
By a straw not yet grasped at I meant k9 pregnancy surprised you haven't used that yet?

                                           Good Lord! ... was Eddie pregnant?

[John]

No more than Eddie would miss a cadaver scent.  Both dogs alerting indicated that blood or blood and cadaver had been found.  Unless a cadaver only dog was used there was no way of determining otherwise.

I beg to differ.  Eddie and Keela were used together for the first time ever in PdL, and we know there was no cadaver odour ...

[Carew]

Both dogs alerting at the same spot does not rule out the possible presence of cadaver contaminant though you said it did.

What is the evidence of abduction ferryman ?

You keep stating it without a foundation of evidence to back it up.

As to the prosecutors, they had insufficient evidence to charge anyone.

[Mr Gray]

I would go further.... A dog not alerting does not rule out cadaver odour

[ferryman]

Well, yes.  There is not a shred of evidence of cadaver odour.

There is evidence of questionable alerts, to clothing in one spot, but no reaction to the same clothing in a different spot.

And cuddle-cat.

When was it shown the dogs did not alert to a body ferryman ?

The principal evidence of abduction is the absence of evidence of anything else.

[Brietta]

According to his book Mr Amaral had already determined that his theory was the only game in town. 

As far as he was concerned, even before the first sniff occurred, there could only be one outcome ... "Their mission: to find Madeleine’s body and expose those responsible." Amaral Chapter 17.

Thus the mindset for the classic mistake of trying to make the evidence fit the theory distorted the outcome, or lack of it, of the dogs visit.
