The dogs are trained to alert to a particular odour.
The dogs alerted eleven times.
All eleven alerts were directly linked to the McCann's.
The dogs are not trained to alert to anything else. Tests show they do alert to what they are trained to alert to with 92-100% accuracy. The dogs are regularly tested.
You can't possibly test which billions of other things the dogs might mistakenly alert to. To suggest that this means they lack proper training or testing is just chaff. The fact remains that the dogs are trained to alert to specific things. To be wrong eleven times would be quite something. To be wrong eleven times and all the mistakes by chance just relate to one family is off the scale incredible.
IMO must people faced with the dog alert films in the context of this case would begin to concede that the likelihood is that the missing child is dead. They would then want to know what has happened. IMO the first response would not be to clam up... and then to rubbish these highly skilled dogs.
The dogs are only tested for their ability to alert to cadaver odour....which they are good at ...but not tested to see how they behave when cadaaver odour isnt present.
grime said no false alerts in 200 case searches....which would suggest they are not tested for false alerts...that is a major fail..imo
The dogs alerted only to articles related to teh mccanns. according to the PJ...cite provided many times...they initially did not alert to things mccann but were called back.
even grime has said that the alerts are not necessarily related to any particular scenario
11 alerts in Jersey...a coconut...baby teeth...and some bone fragmnets that may or may not be human...grime has now said cadaver dogs do not alert to such teeth....so what were all those alerts about
based on the evidence...imo...cadaver alerts total rubbish in this case
