Good point. There's certainly nothing about cadaver dog alerts in the Mathew's household in the piece Brietta was kind enough to post either.
One cites an article when wishing to make a particular point. Which in the instance you quote was not about the false positive alerts made by specialist dogs brought into the case.
It seems the sceptics on this board are now indulging in more rewriting of history by their denial that the dogs did indeed make false alerts in Shannon's case ... to which I now post the appropriate link ...
SnipA South Yorkshire Police spaniel called Eddie was said to have sniffed out the "scent of death" at the Haut de la Garenne children's home in Jersey and the apartment from which Madeleine McCann disappeared in Portugal.
But in both cases nothing more was found and South Yorkshire Police say Eddie is no longer working with them.
Victim recovery dogs from four different police forces were used during searches for kidnapped schoolgirl Shannon Matthews in Dewsbury in West Yorkshire in 2008.
The dogs found evidence of dead bodies, but officers later discovered the corpses were nothing to do with her disappearance.
"The properties searched contained a high level of second-hand furniture bought from dwellings where someone had died," according to the NPIA report.
"This resulted in numerous indications that required further investigation to confirm whether they were connected to the investigation, or to previous owners of the furniture."
The Association of Chief Police Officers told Sky News it was consulting individual police forces and hoped to have national training standards for the dogs later this year.

The dogs did indeed find evidence of death ... but most certainly not Shannon's. Resulting ... as reported ... in time having to be taken out of the investigation to check out the provenance of the alerts which in all instances were proved to have an association with dead people.
The point being that no inference was made regarding those alerts until the police had the evidence to prove the verifiable source. That just did not happen in Madeleine's case thanks to the amateurism demonstrated by those involved in deciding a bark equalled guilt without bothering with the proof of evidence.
