Conspiracy - a secret plan by a group to do something unlawful or harmful.
And I don't "assume" there was a conspiracy, but all the sceptic theories I've seen (including Amaral's) rely upon collusion within the group to conceal the "truth" or provide a false account of what happened.
For example, their collective accounts don't allow for the parents to have had time to dispose of the body and stage an abduction if an "accident" occured to Madeleine during dinner. Their accounts support the notion that everything was normal, nothing was untoward or suspicious about the parents behaviour prior to the alert if you're assuming something had happened prior to dinner. The account of Matthew Oldfield supports Gerry's account of the moving door. The account of Jane Tanner supports the prospect of an abductor. The account of David Payne supports that Madeleine was alive and well that evening etc etc. All of these are things that sceptics point to as evidence of a collaborative deception.
If you have a specific theory that implicates the parent's involvement but does not rely upon anyone else in the group lying, please share it. Because every option I've seen proposed relies on other members of the group being deliberately dishonest in some way or other.
You are doing everything you can to deflect from addressing the uncomfortable questions being posed. Resorting instead to whataboutery or picking on a trivial semantics you think you can contest.
It sounded like an assumption to me; " Point me to another similar case where you can draw a parralel of a conspiracy on this scale to cover up an accidental death."
What if whatever happened to Madeleine didn't happen during dinner?
Was it normal for Kate McCann to ask her friends if she'd made the right decision by leaving the patio door open so Madeleine could leave 5A and find them? After all, according to Russell they'd been doing it since Sunday evening, although Gerry denied that.
The moving door saga suggests there was an intruder before 9pm, then again before 9.30pm and a third between 9.30 and 10pm. What that explains I can't imagine. The change in the bedroom door position after 9.30pm detracts from Jane Tanner's sighting of an abductor at 9.15pm, unless he went back to move it afterwards.
David Payne did indeed testify that he saw Madeleine at around 6.40pm, but not until 11 months after the event. Then we have his questionnaire when he is reported as saying he was in 5A at 5pm when, supposedly, he was at the beach.
