My problem with Martin grime is that during the searches in luz he was ceasing to be a policeman and becoming a businessman. As a businessman he has a financial interest in promoting the alerts as valuable.....that to me provides a conflict of interest. Ive no doubt he believes in the ability of his dogs...but can we rule out confirmation bias.
You know nothing about the man but feel entitled to question his integrity. There's no evidence to suggest that finanual gain was his motivation. He served his term in the police and on retirement he offered his services to those who were willing to pay for them.
Mark Harrison quoted the costs charged by SYP for the dogs in 2007;
costs for the EVRD and CSI are available.
The daily rate for this dog team is 1000 Euros. Flight travel costs for handler and dogs could be 2750 Euros. Veterinary costs: U.K. and Portugal to comply with Pet Passports scheme 450 Euros. Accommodation, subsistence and vehicle transportation would incur extra charge.
