This one is for AZ, please.
In your opinion, what would it take (evidentiary speaking) for the SA to present the theory that Q104 was used to bind Caylee's hands during their case in chief? As LambChop and several of us have noted, binding her hands means only one thing. We've got fringe hairs (that are not candidates for DNA analysis), fibers and a very curious image from the trunk photos. Anything else? I realize that they could throw that in during closing arguments, but I don't know if they would even 'go there' unless they could really convince the jury of that theory.
I think Q104 is a very, very important piece of evidence and if they could tie it to binding Caylee's hands behind her back.... well, that is pretty darn damning, iykwim.
