Now we were in an underground garage where 8 or so cars (actually 10) were parked, including our rented Renault Scenic. It was hard to miss: the windows were plastered with pictures of Madeleine. In medicine we would call this an 'unblinded' study, one that is susceptible to bias. One of the dogs ran straight past our car, nose in the air, headed towards the next vehicle. The handler stopped next to the Renault and called the dog. It obeyed, returning to him, but then ran off again. Staying by the car, Grime instructed the dog to come back several times and directed it several parts of the vehicle before it eventually supplied an alert by barking.
Kate McCann.
(My own addition) At one point in the video, Eddie actually squatted several seconds under the
boot of the Renault, before getting up, wandering off and being called back again by Grime.
The evidence (of the influence of handler-bias) is well documented and actually referred to by Grime himself in his profile.
