Were the dog alerts in any way significant?

[Eleanor]

The science does say they could.

So what about the Transference of Odour?  Not that I think that any of the dog's searches are of any importance.

[OxfordBloo]

Were they not following guidance from the British on this?

They were following Grime.

He was responsible for how the search was carried out and how it was recorded.

[Carew]

Has science shown yet why errors in alerts.... due to contaminants.... blood or non-blood, present at all investigation sites are not occurring on a continual basis, anywhere and everywhere.....rendering deployment of the dogs a waste of time?

Excellent question where why the dog believers claim seems not to accord with science or reality - they make mutually exclusive claims at different times.

[Carew]

That is rather a sweeping generalistion about Carew which would presuppose you know the identity and profession of that particular poster. Even to say "well I can tell by the posts" would imply you had eliminated the possibility that the poster was a wise man taking the piss which would presuppose you knew for sure he wasn't.
That would leave one wondering.

Not to worry...........The flow of supporter prose must go unchecked, otherwise attempted put-downs of all sorts ensue.

If you were holding a cadaver in your hands and then you held CC in your hands that would be a transfer of odour. Any clothes that was in direct contact with a cadaver would be contaminated and Eddie would alert to those items.

And any clothes in contact with first said clothes would also be contaminated.

[DCI]

The Portuguese were totally overwhelmed by this investigation, the screenings in the gym and the car park were chaotic, arranged on the spur of the moment with little thought being given to the way in which the test items were handled.  A unmitigated shambles.

Shambles is correct, Admin.

58 mins, on.  Clothes being laid out, dragged on floor to move across. It's been cut and doesn't now show boxes and suitcases being unpacked.

[pathfinder73]

And any clothes in contact with first said clothes would also be contaminated.

If somebody did die in that apartment they had to touch the body and if they moved it or cradled the body in their arms their clothes would be contaminated.

So contamination or transference only goes as far as you want it to.

Direct contact would be a strong odour. Transference without direct contact with cadaver has to be weaker odour so possibly CC was that example.

We have the apparently perfectly acceptable Cherry Pickers` Convention claims of ...........

Handler cuing and bias,
Cross contamination,
% error,
Expectation of Result,
Handler/ Investigator Combined Wicked Agenda,
Downright Naughty Toy-Grabbing Doggie, playing on the job!
Nosebleeds or Shaving Haemorrhages past and present
Deceased Previous Owner`s Deathbed Pyjamas
Expectation of reward by the dog if he alerts............and all the rest and on it goes.

We`ve had them all.......

Take your pick.........If one rationalisation doesn`t explain an alert away, another will.

The dogs get "switched on" by handler command, don't they?  In other words if their handler doesn't instruct them to alert they won't.  Which is carte blanche for handler bias, conscious or unconscious to come into play, isn't it?

[jassi]

Why should a dog-handler be biased? What benefit is gained by encouraging a dog to respond to a non-existent scent?

Ask Zampo's handler or any of the dog handlers in the link in my sig line.
