thousands of posts re the dogs but no sceptic will answer the question...what do the alerts tell us
that is what is important
I will go with Grime, the man who trained and deployed the dogs. His professional opinion is of value because of his years of experience and his close relationship with the dogs. He tells us what they were trained to find, where they alerted, and what that means
in his professional opinion. He quite properly points out that the alerts have no evidential or intelligence reliabilty without supporting evidence, but he's clear about what he thinks Eddie alerted to. Policemen are very aware of the need for facts and of the dangers of relying on opinion, but he still chose to express his opinion. That suggests confidence in Eddie's abilities.
The tasking for this operation was as per my normal Standard Operating
Procedures. The dogs are deployed as
search assets to secure evidence and
locate human remains or Human blood. The dogs only alerted to property associated with the McCann family. The dog
alert indications MUST be corroborated if to establish their findings as
evidence.
Therefore in this particular case, as no human remains were located, the only
alert indications that may become corroborated are those that the CSI dog
indicated by forensic laboratory analysis.
My professional opinion as regards to the EVRD's alert indications is that it is
suggestive that this is 'cadaver scent' contaminant. This does not however
suggest a motive or suspect as cross contamination could be as a result of a
number of given scenarios and in any event no evidential or intelligence
reliability can be made from these alerts unless they can be confirmed with
corroborating evidence.
