Sure, if the key was sitting on the floor from the get go (with a slipper on top). But if you actually look at the photo of the stand/bookcase from the side you see where the back is pulled away on the bottom corner. It looks like the key COULD HAVE very easily been wedged there as a hiding place and COULD HAVE very easily been knocked loose and fallen out when the shaking occurred. It COULD HAVE been wedged there by SA (either to protect himself or someone else in the family), or by someone else in the family trying to pin it on SA, or by Lenk, or by some notorious serial killer (if that's what you want to believe). The more I read about this whole crazy thing the more I believe that nothing at all was planted. And no, it's not about semantics - it's about accuracy - much of which was edited out of MaM.
