I still don't completely understand. The prosecutor says that it is blood related to the murder. The blog said that there is no DNA so it is not Meredith's blood. If I understand that correctly, then I get the impression that it is really splitting hairs to claim that the prints are not from blood, but instead from high iron content in the water - which we haven't heard about, or from bleach residue left days earlier - and prior to several uses of the shower. The reason that Meredith did not leave the same residue or iron stains, even though she used the same shower, is because hypothetically she wore shoes after stepping out of the shower.
It seems like the blogger is really stretching to distance Knox from the bloody luminol foot prints.
Yes, I agree comletely with the stretching to distance Knox from the bloody footprints. That's why I have many problems with information coming from a site where I have seen with my own eyes how they twist information around to make it appear meaningless or inconsequential (sp?) or otherwise distort the evidence. And admittedly, that happens on both sides (in general, on the internet, not saying on here), so not trying to accuse one side.
I think what Yellow is trying to say is that if that is blood from Meredith, why didn't it test positive, or show, that it had Meredith's DNA? I must admit I find this odd, if this is true. I just don't know. You would expect that if the luminol indicated blood, then obviously it is Meredith's blood, so then they didn't it test positive for Meredith's DNA?
I think that is what Yellow was saying. Correct me if I'm wrong, Yellow.
