IMO that official would not have been MH. And your ideas that MH "turned his back on ...." and that MG "largely disregarded the direction of ...." are incorrect IMO.
If you watch the videos you will see these two experts working very efficiently together.
I have posted this before, but I will do so again.
Mark Harrison's summary of all searches:
The timeline of these searches was as follows:
On 31-07-07 the PJ conducted canine searches with a search warrant at apartments in Praia da Luz that had been previously occupied by the McCanns and their friends.
On 01-08-07 the PJ and GNR assisted by a canine, conducted searches on the eastern beach and wasteland in Praia da Luz.
On 02-08-07 the PJ conducted a search warrant at a villa in Praia da Luz currently occupied by the McCann family.
Later the same day PJ officers conducted a screening procedure involving items removed from the McCann’s villa.
On 03-08-07 PJ and GNR officers were given instruction based on translated extracts from NPIA doctrine on search management and procedures. This focused on search procedures relating to buildings and vehicles.
On 04-08-07 and 05-08-07 a search warrant was executed at the villa and gardens belonging to the PJ suspect Robert Murat. This search involved both PJ and GNR personnel supported by civil defence, geophysical equipment operators and a canine handler.
On 06-08-07 ten vehicles were searched associated to the enquiry.
On 07-08-07 the western beach and remaining wasteland areas were searched using canine and GNR personnel.
On 08-08-07 the drains around the apartment block where Madeleine McCann disappeared from were subject to a visual inspection by PJ officers.I
don't think it coincidence that Grime acknowledges the input of Grime and his dogs in those searches
he recommended, the places Madeleine either had been or (conceivably) might have been, the holiday apartments, areas in and around PdL and the Murats' place.
Both inspections at villa and gym, Harrison summaries as
PJ exercises.
And while Harrison
did recommend an inspection of vehicles, only 2 (of 3!) vehicles he recommended be inspected made the final line-up of 10.
The exception was a vehicle Murat hired that never made the line-up; while 8 vehicles Harrison never said anything about made it (including the Renault Scenic).
Harrison gives no clue who took part in that exercise.
And Harrison waited until after both inspections at villa and gym to give PJ officers translated instructions on how to conduct inspections in vehicles and buildings ...
