Somewhere amongst the statements (haven't got time to look at the mo) the question is asked of Martin Grime whether the varying levels of intensity of the dog's alert is relevant (words to that effect). Martin Grime assures him that 'the dogs either alert or they don't.' And yet when Eddie only barks once in the garden Grime states that it was a 'weak' alert. That seems to be a direct contradiction of his previous assertion.
'Based upon the dogs' behaviour, is it possible to distinguish between a strong signal and a weak signal'.
The dogs' passive CSI alert provides an indication as per their training and does not vary. They only give an alert when they are 'positive' that the target of the odour is present and immediately accessible. If they had any doubts they would not give an alert.
EVRD gives an alert by means of a vocal bark. The variations in the vocal alert can be explained by many reasons such as 'thirst' or 'lack of air due to effort'.
To begin, I thought that line of questioning might have been prompted by Eddie's alert in the garden, which was more of a whimper than a bark.
But I now think it more likely to have been prompted by the inspection in the gym, the only justification for which in the files seems to be to re-test clothing (sic) "possibly alerted to in the villa".
That inspection, even more than the one in the villa, wreaks of something unsavoury and underhand.
I wouldn't be at all surprised if the questioning was prompted by our old friend Inspector Dias, who is my absolute PJ hero in the Madeleine investigation.
