OK then. I think it's disgraceful to say that the PJ faked alerts.
It has never been my opinion that the dog alerts were faked in any way whatsoever. From first sight of the video I formed an opinion that something was amiss in the thinking of those who set such store by them.
That observation and subsequent reading of what Martin Grime clearly stated regarding the alerts convinced me that ignorance, incompetence and a total lack of understanding ~ not 'faking' or dishonesty ~ was the hallmark of this particular team of PJ inspectors.

Q: 'In order to establish the accuracy of the dogs' performance with respect to the alerts given when recognizing blood and a body, to what extent are these indications viable in this particular case''
A: The dogs' alerts are to be considered as an area of interest or possible testing.
When specific and reliable this can only be measured for confirmation.
In this case in particular, where the dogs alerted there was confirmation by positive results from the forensic examinations.
It is the investigators' responsibility to apply the results of the forensic analysis to the suspects, witnesses and crime scenes.
--------------------------------------------------------------------------------------------------
Every alert can be subject to interpretation, it has to be confirmed.
The signals of an alert are only just that.
Once the alert has been given by the dog, it is up to the investigator/forensic scientist to locate, identify and scientifically provide the evidence of DNA, etc.
---------------------------------------------------------------------------------------------------
There is always a possibility of contamination of odours by transferral.
EVRD does not make a distinction; he responds with a certain behaviour for which he was trained when he recognizes an odour.
He does not identify the reasons for the presence of the odour nor does he identify suspects.
Forensic confirmation and specialized investigation methods will determine the reasons and the suspicions.
In order to undoubtedly affirm there must be a confirmation of the alert signals made by the dog.
