But what about the window? No, I'm sorry sadie, but this all sounds a bit *** to me.
Purleaze, WS. This has been gone through at least 6 times by me personally and by others over and over. There were at least 6 sensible reasons why the window was open:
1) to have someone outside who could give verbal support to the lifter and pass things such as chloroform through the window
2) that someone only had to take on step back in the walkway and he could be in visual contact with the watcher on the balcony across the road. A signal could easily be given such as a glowing fag or even a torch beam, if someone was coming. With the window open the lifter had two choices of rapid exit . Either through the front door or out through the window.
3) To clear the bedroom of any scent of Chloroform
4) To give the impression that Madeleine had left of her own volition
5) If a key had been "lent" to the perps, then having an open window would persuade the investigators that the window was the means of entry and let the O.C. staff member key-lender off the hook. The window wasn't used for entry or exit; the front door was
6) I can't recall any other reasons that the window was open but there were at least another.
now WS you have the possibilities and likelyhoods.
Please DO NOT WASTE ANY MORE TIME repeatedly re-asking this question.
Annoying and time wasting, but it did give me an opportunity to tell people new to studying the case, the likely reasons that the window was open. So thankyou for that

You scored an own goal, didn't ya!
