But any chink in the book's armour unfortunately weakens their argument.
There's another one too, in my view: a photograph taken where an allegedly innocent, recently graduated school teacher was shot as he fled the carnage. It shows spent cartridges, and in my opinion it and the caption with it suggests they came from SAS snipers.
The authors today denied creating the impression that the shell casings were from SAS weaponry.
Well, an examination of the cartridges shows they couldn't have possibly come from the SAS, if they'd fire them they at the very least would have dislocated their muscular shoulders.
Weapons expert Richard Munt from Auckland, without knowing the background of the photo, says they probably came from Apache helicopters.
Guess what was accompanying the SAS on their raids? Yep helicopter gunships, under our control, but flown by Americans.
Perhaps that gives weight to the theory put forward by Mr Responsible, the country's most experienced Cabinet Minister Peter Dunne who knows how the machinery of Government works.
