A Good, Bad or Average Theory What's The Difference?

[Mr Gray]

I think Davel is trying to say the only evidence that's useful is forensic evidence. In that case what forensic evidence were they hoping to recover from the family's clothes?

I think its obvious to all you are wrong and thats not what I think...there are lots of types of evidence...vrd dogs barking isnt one...imo the alerts being evidence is a sceptic core belief and the major reason they have reached the wrong conclusion

Well don't be shy, just explain the purpose of screening clothes.

Whos idea was it... I dont see the point... Was it the idea of the PJ

I was just reading Grimes statement... He says when passing the mccanns car the dogs behaviour changed substantially

Didn't the dog initially ignore the car.... What is grime on about

In the hope and expectation that they would alert thus putting pressure on the McCanns to confess, IMO.

You may not see the point, but there must have been one. There would have been no point in carrying out a pointless exercise. So what forensic evidence were the clothes going to provide?

No, my friend, you are. You insist that only forensic evidence is useful, but it was never going to be detected on clothes. The only possible evidence from screening clothes was circumstantial evidence, and that's what they were looking for and that's what they got.

absolute codswallop....i have not insisted only forensic evidence is useful...

The alerts have no evidential reliability...circumsatntial or otherwise.

I suspect it was the inept PJ who decided to screen the clothes...and the mccanns car

As Keela was the first dog deployed to screen the clothes in the gym, it stands to reason that minute quantities of blood were being looked for. That was Keela's sole purpose during training. It's unclear why Eddie was then deployed to check the clothing again, given he hadn't alerted to any of the clothing during the earlier VRD screening exercise at the rented villa.

[pathfinder73]

It's obvious why Keela went first because both dogs alert to blood. Only Eddie alerts to cadaver scent so he had to go second.

The dog will alert to the presence of cadaver scent whether it is at source or some distance away from a deposition site. This enables the use of the dog to identify the venting or exhaust channels of the scent through fissures in bedrock or watercourses. A geophysical survey of the area will then reduce the size of the search area. The dog may be used to screen clothing, vehicles or property in a suitable environment.

Eddie was always deployed first, except for the clothing screening which took place in the gym. As Eddie hadn't alerted to any of the clothing at the rented villa during earlier screening, why was he deployed again at the gym in the absence of any alerts from Keela?

[pathfinder73]

Yes and that's for obvious reasons because they want to know if there is cadaver scent at the crime scene in a suspicious missing person case. As there was then they can take items belonging to the people who lived there to test for cadaver scent so now they rule out blood first on clothes because if Eddie then alerts they know it is for cadaver scent. That is why cadaver dogs are used and the police have a prime unknown suspect carrying a deep sleeping child who the Smith family believe was Madeleine McCann.

The chain of evidence between clothing/personal effects in 5A & the gymnasium had been broken several times by August 2007 when the specialist dogs arrived.

[pathfinder73]

The same family lived in both properties with their belongings so police should further investigate leads.

Cadaver scent cannot readily be removed by cleaning as the compounds adhere to surfaces. The scent can be 'masked' by bleach and other strong smelling odours but the dog's olfactory system is able to isolate the odours and identify specific compounds' and mixes. Cadaver scent contamination may be transferred in numerous scenarios. Any contact with a cadaver which is then passed to any other material may be recognised by the dog causing a 'trigger' indication.

Why would any organisation pay someone to look for and find information which is completely useless?

Psychological pressure applied hoping for a confession.
