I see you have no explanation as to why there were no alerts in places where it is impossible for any reasonable person to believe that not a drop of blood or any other material capable of being detected by the dogs - had ever been deposited - over years and years - involving hundreds of people.
I have already 'confronted' M. Grime - in the form of a question elsewhere on this forum. I am still awaiting his reply.
Any such explanation would need to include the reasons why non-stop alerts from start to finish during
any investigation
everywhere do
not occur......despite pork, lavatories, nosebleeds..... and all other residues found in the everyday work of the woofie on duty.
As I said, do we insinuate it`s all down to handler bias, cuing to alert or not to alert , all of which malpractices are glaringly obvious to those such as yourself ........( The handler doesn`t fool you! It apparently only needs good eyesight and common sense to have him bang to rights.)........
.........or do we accept that you aren`t the expert and request that you stop smearing those who are ?
