Yikes! I'd say you have questions!
I take it you weren't very convinced by the reconstruction by Ron Hendry and the numerous probable answers to those questions in this and previous threads? That stuff bores me to tears personally, especially as I don't see what it has to do in the slightest with Raffaele or Amanda being involved in the murder. There's no evidence they were responsible for any of that, and I'm quite frankly not all that interested in retracing Rudy Guede's movements footstep by footstep as he kills a poor girl and cleans himself up. I'm leaving that part out of my 'movie.'
Are you of the opinion that without any evidence whatsoever Raffaele and Amanda were responsible for them, it still somehow implicates them? What if Rudy had done a real clean up, would that damn both Raffaele and Amanda automatically? Are you deeply suspicious of the covert operations of the lamp as well?
You know, they only tested the toilet paper for Rudy's DNA, the dump in the bowl went untested, thus it might be Raffaele's or Amanda's!
What makes you think they were blood? Do you think Stefanoni lied about seeing the chemiluminescence pattern? Because if she didn't, then they can't be blood, they wouldn't glow like that if they were diluted to less than 1:1M (million) to fail the TMB test. If she lied about that, it would imply she not only failed to mention the negative TMB test, she also deliberately deceived the jury in order to pretend those footprints could have been blood. Being as they also could have found a way to attribute Amanda or Raffaele's foot to my avatar if they wanted to with that pattern of mendacity, doesn't that implicate the prosecution more so than the lovebirds cuddling a half-mile or so away?
It's kinda like the difference between spilling water on your carpet that has a splash of soda and maybe looks a little cloudy and dumping a glass of pure coke on it. You can scrub up the latter as best you can, but there might still be a bit of a stain, whereas the former you could probably let dry and never notice.
