The S&R dogs scent off skin rafts which we all shed at the rate of 40,000 per min. If MM was placed in a car (airtight) within the immediate vicinity her skin rafts would no longer be available for the dogs to scent on and imo this is what happened.
GA took note of them its one of the reasons he was dismissive of 'Tannerman' rightly so imo.
The S&R dogs deployed on 4th May are going to be more reliable than those deployed on 7th May.
Cars are not airtight ... just think about it.
Dogs are capable of tracking a person travelling in a car ... check that out using a search engine.
Ignoring evidence without checking it out is in my opinion sheer incompetence.
The sniffer dogs brought in from Portimao on the fourth were essentially patrol dogs ... I recommend you read the report requested on
3rd December 2007 ... obviously requested by the new coordinator, Amaral having been sacked by then apparently without bothering too much about dogs other than those which don't lie.
If Amaral rubbished Jane Tanner's sighting because the dogs apparently ignored the route taken ... why did he fail to act when the dogs showed obvious interest outside the empty apartment 5J.
Wee bit of a contradiction there I would think.
