The table is key to this case. And Greer proved it today with the mannequin demonstration. It looked pretty clear that Rebecca was hanging very low to the ground and a table wasn't needed. In fact pulling that table over was a time wasting thing, on top of it being so much more complicated to cut her down, when all he needed to do was walk up to her and cut her down.
RZ was hanging very low to the ground, I believe it was testified that she was 20 inches from the ground. Seeing that distance displayed in the courtroom today was huge, because for someone wanting to jump off a balcony, that is cutting it really close to actually make contact with the ground and instead of a "suicide" it would be some broken legs. Also, in my opinion, the reason why the bed wasn't moved the distance it should have been moved with a hanging death, is because if the bed was moved any more, she would've made contact with the ground. In my opinion, AS moved that bed himself knowing it should move in a hanging death, but he couldn't move it as far as he wanted to because she would be too close to the ground....he had no wiggle room.
This is all my opinion, but its the reason why I think the demonstration was huge today and why I think the table is one of the most important pieces of evidence in this case.
