I used the word “strong” because forensic science journals say the dogs accuracy at alerting to cadaver odour is 92-96%. Now you will next say; “ah but what do they do when there is no cadaver odour?”. I would suggest to you that in these circumstances they don’t alert. I’m sorry but currently I can’t tell you what the research tells us for percentages of false positives. What research I have seen shows the percentage of correct positives.
Given Dave’s keen agenda to trash the dog alerts in this case, I would ask if Eddie false alerts all over the place why does he only alert in the one apartment. 5A where a missing child has never been seen since and where Keela also alerted and correctly identified where it proved possible to recover forensic samples of human blood.
I know you will also dispute it was blood. We will have to settle on “human cellular material” . In my opinion if the FSS are not able to distinguish a blood cell from urine then they don’t sound like they were fit for purpose!!
I think you are totally mistaken. Just because the dogs have a 90%+ rate at detecting cadaver in test conditions does not translate to such a success rate in the field. good to see you were posting your opinion as fact....i noticed that straight away. it seems a certain mod didnt.
Why did the dogs only alert to items McCann...simple...and its nothing to do with cadaver odour.. its time.
Eddie totally ignored the McCann car and was callled back 3 times...watch the video. he was not called bvack to any other car. according to the file as recorded by the PJ...the same thing happened in the apartment.
Im not suggesting Grime is a fake....im just stating facts.
Talking of science theres a recent study from the University of california re false alerts. It says taht teh dogs are so sensitive they can pick up body language from their handler so perhaps it was Grime who was excited going into 5 a and eddie picked up on this. It says the handlers are totally unaware of cuing their dogs.
re the time taken for eddie to alert.....there is talk of dogs scenting passengers for covid at airports. it says the dogs are accurate and two dogs can handle 300 persons in under 3o minutes.. That flies in the face of the time eddie spent searching before alerting.
You and others think i trash the dogs...not true. Gunit posted an ACPO pdf re detection dogs. it talked of victim recovery....and not one word about remnant scent. The job of these dogs is to search for bodies and body parts.
It seems to me it was Harrison and grime in 2005 who decuded that the dogs could be used as intelligence in murder and abduction cases.Nothing wrong with pushing their own agenda ...perhaps that too is unconcious.
so my aim is not to trash the dogs....but get to the truth about what happened to Maddie...quite a laudible aim and nothing wrong with challenging evidence taht took the initial investigation totally in the wrong direction...
final thought...the job of the dogs is to help recover evidence...posters need to remember that. The fact is the dogs found nothing of any use
