I wanted to also comment about the windows below. See there are so many physical issues that bother me about this whole alleged suicide. But first about the concept of swinging into and breaking the windows below.
A "suicide leap" from the master bedroom desk would have been a totally different physical dynamic. The balistrade on that deck is extremely low. You could actually hop over it (maybe even with your ankles bound!). So in the case of the side deck she would have had a near straight vertical fall, most likely feet first. There would have been very little swinging involved.
Compared to....how we are being asked to believe she chose to do it. In a far more complicated, difficult (I believe the physics show near impossible) manner of rotating her body over a 38" high balcony rail. In the case of the guest bedroom balcony, her body MOST DEFINITELY swung once it hit the end of the rope and I would be surprised if her feet did not strike the side of the house.
What nobody has been able to give me is a logical explanation for why, if you have chosen to perform the difficult task of propelling yourself over a 38" rail, when you're only 5' 3-1/2" tall, you would decide to bind your ankles and make it more difficult. And "symbolic" don't work for me as an excuse.
People keep coming up with the phrase "you never can tell how a suicidal person might think" to cover every single thing that is bizarre AND would require this woman to consider a myriad of factors. Problem is, if you apply that reasoning to every issue discussed (like - omg, I might break the windows!) you end up turning Rebecca into a MacGyver...a friggin genius whose mind ran through a matrix of parameters prior to her finalizing her own ending.
I can see binding your ankles if you are looking at what is the more "typical" (I guess that's the right word to use) indoor hanging suicide where you basically tie yourself off to a closet rod or something and then step or hop off a chair or table. In that case, like the bound wrists, you COULD try to save yourself if your feet are free.
You can't do squat with your feet once you've dropped 12 foot from a 2 story balcony. I'm sorry, but the binding of the ankles is virtually impossible to explain in a suicide conclusion.
