OK what does Kate McCann say in her book about the cadaver dogs?
"Gerry and Kate’s reaction to sniffer dogs hitting on McCann holiday apartment and rental car ‘didn’t make sense’"
http://www.cadaverdog.net/gerry-and-kates-reaction-to-sniffer-dogs-hitting-on-mccann-holiday-apartment-and-rental-car-didnt-make-sense/"US criminal profiler Pat Brown, who for almost a decade has studied the case and written extensively on Madeleine’s disappearance, described Kate and Gerry’s reaction to the sniffer dogs as “just not right”." I don't think Pat Brown gets it right in this case.
"Brown believed it strange that the McCann’s did not appear “very concerned” that the work of the dogs indicated a dead body had been in their Algarve holiday apartment."
"During a 2009 television interview with Portuguese journalist Sandra Felgueira, Gerry McCann was asked about the cadaver dogs alerting to the scent of a dead body in apartment 5A and their rental car.
“I can tell you that we’ve obviously looked at evidence about cadaver dogs and they’re incredibly unreliable,” McCann replied.
Kate McCann made similar assertions in the book she wrote about her family’s ordeal, titled Madeleine."
Saying they are unreliable is that contesting the result? I'm not convinced. I'm still not convinced they are denying that there was cadaver odour in the apartment.
