He says he did mention the twins abnormally sleepy state though didn't he? He said he thought it was strange, so why didn't he question it when he was there?
He did mention it but why would he if he knew he may be accused later of not acting on pleas from the children’s mother ? Why not pretend he didn’t even notice ? As to why he didn’t question it could it possibly be because the parents weren’t questioning it ?
So to round things up. Neither of the parents claimed at any time before Kate’s testing request, while Gerry was in Washington, that the twins had been sedated. Although the parents asked the FLOs if any substance had been used to facilitate their daughter’s abduction they did not tell them of their worries that the twins may have been sedated ( remember Kate’s alleged frantic requests for help on the night) or ask that they be tested. Of course if the twins had indeed been sedated the substance used could have helped in identifying a perpetrator. Not one of the people surrounding Kate that night, not even her husband, claim they witnessed Kate asking for help. The only translator present was not asked to translate Kate’s alleged pleas to the officers.
There is absolutely nothing to suggest Kate raised any concerns on the night that her children had been sedated and to claim she did in the face of overwhelming evidence to the contrary is simply sticking your head in the sand.
