Are Victim Detection and Forensic Evidence Search Dogs reliable?

[Mr Gray]

i.e. No he didn't.

he said the alerts were suggestive...he never claimed they positively indicated cadaverine...its there in the files

I have read some time ago what he said davel.

I am also aware of the relative probabilities of successful alerting by the use of dogs.

P.S. Why this fixation with Pentane-1,5-diaamine/1,5-Diaminopentane. There are many other compounds produced during decomposition ?

Meanwhile, back later after work.

So your earlier claim that the McCann's have never rubbished the dogs has now been shown as totally incorrect. Then again as you make a frequent habit of excusing the McCann's actions you have at least stayed true to form.

It's just a shame that it does nothing to help the credibility of your posts.

Gerry said the dogs are unreliable...you cannot tell me how reliable the dogs are...perhaps Gerry was telling the truth...I get PMs saying what a good job I do so some appreciate my posts...of course when I point iut where posters are wrong...it doesn't make me popular with them

Here's a hypothetical question. On 31 July what if not just 1 EVRD but 5 had checked that apartment (each EVRD seperately of course). Would all 5 have signalled? Or just 1 out of 5?

All 5 would have alerted. Grime noted Eddie's change in behaviour as soon as he got to 5A.

If grime was so sure...which I don't believe he was...why was his report unsure

All 5

Thank you to everyone who has already supplied questions for Mr Grime. There are quite a few at the moment but if anyone has any final requests please send them to Mr Moderator.

Migaloo is a black labrador retriever ... She works with archaeologists ... holds the world record for the oldest bone discovered by a dog after digging up a 600 year old human bone buried more than 6 feet under ground ... The previous record was a 425 year old human bone set 25 years ago by a cadaver dog named Candy. ... Migaloo was able to find the first of four burial sites in under a minute. “She was spot on” ...

Thanks for the link pegasus

These dogs really are splendid

In the Lawrence case, the dog deployed on Tyneside is a black labrador called "Candy", and the dog deployed in York looks like the same dog to me. Anyone know who Candy works for?

Nothing much wrong with the dogs. 

Grime is basically sound altho he definitely did make one mistake (with Cuddle cat) and many of us noticed that he kept calling the dogs back to the Mccann car when the dog had not been interested.  That was something he didn't do with the others cars. 

But Grime took the trouble to explain exactly what the alerts DID mean and what they DID NOT mean



Amaral is the problem. 
He either did NOT understand what the alerts actually DID mean and  DID NOT mean ....... or He chose to ignore their true but limited meaning

Nothing much wrong with the Brirish part, The dogs and Grime were OK, but

Everything wrong with Amaral and people who still pretend that the dogs marked death ...., when surely by now with all the explanations they have the necessary brain cells to understand. 

It aint rocket science

And just like that, the entire PJ investigation has been written off as pretense.

Regardless of the fact that the original investigation has been checked and rechecked by Operation Grange who, after four long years, have ended up digging 100m front 5a's front door....EXACTLY where the PJ left off.

do you find it amazing that the investigation is centred on PDL...the last place maddie was seen...where did you expect SY to begin their investgation..outer mongolia?

But that's my point.

This is NOT the "beginning" of their investigation, is it?

It is the END of it.  Or, the beginning of the end, to be more accurate.

Two years of review led to Op Grange.  Op Grange is now 2 years old.

It's not the "beginning", not even close.

My theory: routine change 6-30 to 7pm. Moved at 9 - minimum 2 hours in 5A.
