Dog Alerts- Evidence or not?

[Mr Gray]

As dogs can smell things that humans can't, it's possible that dogs can detect the scent immediately.

Didn't you read the cite you asked for

[G-Unit]

It is only at the later stages of decomposition that the compounds in a rotting pig emits a gas that smells like the gas of a human cadaver also in the later stages of decomposition.   Therefore Eddie didn't scent cadaver in 5a as no way if Madeleine had died in 5a would she have been in the later stages of decomposition before removed from 5a.

Not necessarily. It was only in the later stages that scientists were able to isolate certain compounds that the cadavers have in common. Obviously dogs have alerted to places from which relatively fresh cadavers were removed. How about Suzanne Pilley?

Oh dear... Prof Cassesella questioned the validity if the alerts

Eddie wouldn't have as Eddie was trained on dead pig.    Don't tell me that Eddie could miraculously be changed from detecting dead pig to suddenly be able to detect a human cadaver,  the only way that would happen is if the human cadaver is in the final stages of decomposition.

Oh dear... Prof Cassesella questioned the validity if the alerts

Did he though? He confirms that they're widely used (Ep7 - 06.30), confirms that they're alerting to whatever it is their trained to alert to (07.47), then accepts that a conclusion must be drawn (08.42), where they are to be trusted or is the dog 'having a bad day'.
At no point does he question their validity - he suggests the enforcing authority must draw that conclusion. But bear in mind, they had reason to bring them in the first instance, then they do indeed provide an 'alert' in the place they suspect, in this case all parties - police, procurator fiscal, prosecution, judge and jury all drew their conclusions independently, as John suggested they do. Et petit pois, bonjour.

There are people who question the validity of dog alerts and people who support their validity. It must be a source of annoyance in my opinion that forensic scientists can't explain how these dogs do it.

I think you are in total denial.... It's the experts.. Prof Cassella... Mark Harrison... Martin Grime ...who have questioned the validity of the alerts

More nonsense because all cadaver dogs alert to pig cadaver. If you think SY murder team are investigating a missing pig then dream on.

All cadaver dogs alert to pig cadaver only in the last stages of decomposition.    Madeleine if she had died in 5a wouldn't have been left on the floor until she was in the last stages of decomposition.

So the dogs must have alerted to........the rotting carcasses of pigs - only in 5a apartment.

No, Eddie just wanted his tea,behind the sofa, in the closet, in the hire care & on some clothes.

He wasn't hungry anywhere else.

The GNR's sniffer dogs on the other hand, they are infallible, they're the ones you should have total faith in.

It's much simpler than that... It seems the dogs alert when called back three times....

So are you suggesting that Martin Grime is a fraud?

[Mr Gray]

Absolutely  not I think I understand exactly why he did it

[The General]

I don't think he did do it. I think you're exaggerating.
