I'm not suggesting they tested the twins that night, but when it became apparent that a crime had most likely been committed don't you think they should have at least considered the possibility that the twins who were in the room at the time might have been interfered with in some way?
Why?
The Lisbon CSI team tested for anaesthetics on Madeleine's bed on 4 May 2007 and found none.
And while I accept the gassing story was on Richard and Judy prior to May 2007, and so may have been a source for the McCanns, there is also the issue of whether the Lisbon CSI team 1) should have been aware of this tale and 2) should have conducted tests beyond that which they carried out.
The team was not in communication with the McCanns, as the McCanns had gone to Portimão re statements.
And the McCanns raised sedation (or whatever) with the FLO's after the CSI team had departed.
There are times in this forum when threads take on somewhat unreal properties, and it strikes me this is one of them.
The McCanns left the twins in Luz on 4 May. One assumes that was because the twins were fine, as in showing no sign of having been drugged. To imply otherwise would be to libel the McCanns.
There was no insistence that the twins should be tested. Presumably because the twins were fine.
This potentially key piece of information was not entered into statements on 4 May or 10 May. To suggest 'would', 'could', 'might', 'ought to', 'possibly' is to libel a wide range of people, including the McCanns, other members of the T7, one or more helpers on the night, one or more official translators, several PJ officers, possibly some GNR officers and possibly the FLO team.
Bear in mind, this entire thread is hanging off a sensationalist headline in a tabloid newspaper dating to a time when the picture was about as clear as mud.
