Is this another example of a potentially crucial error by the VRD handler?

What was the basis for Grime stating where Eddie had alerted to a specific area behind the sofa and what happened next?

That's for him to know and you to find out. No doubt he had his reasons.

Grime stated the reason on video. I'm curious to know why G-Unit believes the  location of Eddie's's nose bore no relation to what happened next.

I wonder why it was felt necessary  to video the dog searches

Are you trying to convince me you're right by asking me questions? Just make your case.

I guess they can be used to study & improve on handling techniques & training, a well as for evidential purposes. I recall reading that there was several videos on the UK Police Database showing the dogs in action on previous cases.

Grime's own words on the video re. where the dog was scenting heavily - i.e. he had his nose near the spot. Eddie didn't stop at the area under the window a second time, he bypassed it & went to the r/h end of the sofa.

Probably many years of experience.

How long had Grime been handling cadaver dogs & how many dogs had he handled?

Please keep the debate polite and sweet. Thank you.

When you can prove that Eddie's nose position is connected to his alerts you might have a point. In my opinion that's not how Eddie worked.

Was Eddie's nose position not a determining factor in Grime's assessment of the source of the delayed alert?

There was no deposition site in 5A.

That is the big $64,000 question.

You tell us.

I'd imagine the reaction time to a smell is around 0.5 seconds.

I have not been able to find an actual study on this topic but looking at this training video it seems the decision making process takes a full second or two. https://youtu.be/KJZ7rlP77zY?t=94
1:41 is her first pass over the cover, and 1:44 is when she lifts her paw to scratch.  I'm sure a trained dog following a scent trail will be faster than this.

Grime said 'strong scenting'. It's not just where the dog's nose is that matters, it's when he's using it. The handler watches and listens, because a dog which is scenting strongly can be heard sniffing.


what I saw was that approximately in the centre of the wall where the window is, just along the tile area between the tiles and the wall, he's been scenting there a lot stronger than he has anywhere else and the when he's gone out there the second time he has decided yes that's what I'm looking for and that's when he has given me the bark indication.
