Thanks for the posts today Sarx and Oriah.
Correct me if I have summarized this incorrectly, but it sounds like there are some very highly trained dogs (the best of the best) that may not be known to some of the "experts" used by the defense to cast doubt on this HRD dog hit made in the Irwin home. The fact that it was an FBI dog that made the hit makes it quite possible it was one of these very highly trained dogs.
What particularly makes these highly trained dogs special it appears is that they have been trained to differentiate between the smell of blood that came from a live human vs a dead human, and I would assume fecal matter as well. This is particularly impressive to me, because as we see with the interviews by the lawyers for DB, they want to make it sound like the dogs can't make this differentiation.
Basically, it sounds to me like the dog is a variable in the equation that makes the odds of this hit go from a "there was a dead body here" to "there may have been a dead body here, but it could have been blood, fecal matter, or something else from a live human."
In other words, the odds go down. Perhaps it is 95% likely with the best dogs in the business, and it is 75% likely with a lesser trained dog. Obviously I don't know the exact odds, just trying to assimilate the information coming out today because it has caused a little confusion for me.
Is that a correct conclusion on my part?
BBM:
That is correct, at least in my experience.
If- as a SAR handler/trainer, I can produce in court logs of both the consistancy of my training methods, as well as my dogs history of accurate alerts; as well as the certifications that particular dog has- a HRD 'hit' logged by myself is going to hold up a lot better should a case go to criminal court, and a HRD dog alert be called into question.
