In the COLP interview Davidson is shown forms purportedly filled in on the 7th of august when at whf gathering and listing evidence.
Davidson admits he filled in the form...which more or less makes it fairly clear he was actually there.
he states "I filled these in, Dave Hammersley is the searcher".
Statement analysis comes into play here...the present tense "is" being used strongly supports this claim to be a deception. Davidson should have used the past tense "was".
This supports the view that Hammersley was not searching at all because he was not there.
oh ,just prior to this Davidson had said he had found and located the articles and that Hammersley filled the form in...when shown the form he changed his mind as it was in Davidsons writing.
This supports the view that Davidson was both doing the finding of articles and writing them down and covering for the absent Hammersley.
