These aren't "gotchas" or whatever other little pet name you want to call things these days Kevin-Lowe, and I really don't know why such a large number of your comments have to be so rude and arrogant.
I feel the term is appropriate. If you find my use of that particular term rude I regret that.
However it's worth emphasising that here at the JREF forums ridiculous ideas and arguments are fair game for robust criticism. I find all of these "gotchas" ridiculous and I see a moral obligation to explain their ridiculousness.
And because you claim not to understand why Amanda would lie about the door being closed, how about considering the possibility that she already knew what lay behind it.
I already addressed this potential response. See what I wrote above about "guilty knowledge".
You still aren't addressing the elephant in the room, the time of death.
I find this akin to arguing with someone who believes that a dragon is hiding in his house even after we have proved that dragons do not exist, and keeps presenting arguments like "But a neighbour said they saw a puff of smoke, how do you explain that?" and "If there is no dragon in my house then why is some of my cheese missing?".
I think if you just accepted for a minute that dragons don't exist, you could make up your own theories to account for a puff of smoke and some missing cheese on your own that would be as serviceable as anything I could give you.
If you assume for a minute that Amanda and Raffaele were at home watching Naruto until 21:49 or later and Meredith died at 21:30 or earlier, are you genuinely incapable of explaining from that perspective how they might have made two conflicting statements about the state of a given door?
It's an identical puzzle to ones like "How could Filomena and the postal police possibly have made statements that conflicted with each other, or with verifiable facts like the time at which phone calls were made?". If you can crack that one then you should have no difficulties with the "gotcha" about Filomena's door.
