More misdirection by you, Vixen. Whether the Luminol traces were made from Meredith's blood has NOTHING to do with " Body language. Demeanour. Witnesses in person. Physical exhibits. Highly detailed, intricate, complex presentations." It is entirely based on science.
Here are five key questions to ask;
1. Did Massei & Nencini consider the Luminol traces as evidence of Amanda tracking Meredith's blood?
2. Were three of these samples taken from Amanda's bedroom?
3. Did all three traces test negative for blood using TMB?
4. Did all three traces test negative for Meredith's DNA?
5. Did all three traces test positive for Amanda's DNA?
The answer to ALL of the above is a resounding YES. (if you disagree then please advise which ones).
So then here is the one question that you and every other PGP for the past 9+ years have avoided answering.
How can those traces be Made from Meredith's blood given the answer to #'s 3, 4 and 5 above are all YES?
Can you answer that? Yeah, didn't think so.
And here's something I KNOW about you. You will once again avoid the question because you CAN NOT answer the question. You KNOW those traces could not have been made from Meredith's blood but to admit that means you know Massei and Nencini's conclusion was wrong - something you will NEVER admit to. What a quandary for you!
If I had to guess, you will come back with one of the following;
1. You will remind everyone that this is what Massei and Nencini ruled while entirely ignoring the impossibility of their conclusion based on the science.
2. You'll ask "if not blood, what". This is not an answer. The burden of proof is on the prosecution, especially when the science confirms it is not Meredith's blood.
1. Yes, it is believed Amanda tracked Mez' blood into Filomena's room (where the staged burglary took place).
Apart from Guede's bloody footprints, all of the blood evidence outside of Meredith's bedroom was dilute, indicating that it was spread during and after washing. Five traces of Knox DNA mixed with the victim's were found at the crime scene: three in the bathroom (along with a Knox-only bloodstain on the faucet Knox claimed not to recognize), a mixed sample in a Luminol trace in the hall, and in a Luminol trace in Romanelli's room.

This is because Amanda's DNA occurs in the exact spot where Mez' spilt blood was found in a small area.
As for whether any of the others showed Amanda's DNA:
Finding 1 / L5 / Rep. 180
Located in the bedroom of Amanda Knox this was identified as the right foot most likely in a deposit of haematic substance. The 1st toe, 3rd toe, the metatarsus, and a portion of the plantar arch led the technicians to conclude that the footprint was compatible with Amanda Knox's right foot.[8] This trace was also found to have Amanda Knox's DNA.[9]
There is also a luminol-highlighted footprint compatible with Raff:
Finding 2 / L7 / Rep. 181
(Pictured above) Located in the corridor in the direction facing the exit was the print of another right foot made imprinted by a deposit of blood.[10] Next to the right foot was a print (L6) made by a left foot but there were no useful details for identification purposes.[11] The right foot did provide useful information. Being placed on a Robbins grid the investigators were able to get measurements for the big toe, both width and length for the metatarsus, and a width measurement for the heel.[12] The bloody footprint was determined to be compatible with Raffaele Sollecito's right foot.[13]
Then we have yet another footprint identified as Amanda's:
Finding 7 / L9 / Rep. 184
Located in the corridor directly in front of the door to Meredith Kercher's room and pointing towards the entrance as if entering the room.[14] Measurements for the big toe, metatarsus, and heel were found to be compatible with Amanda Knox's foot.[15]
Luminol is used by Forensic Teams to highlight blood. It is not reasonable to claim the substance is not blood. And even in the vanishingly remote chance it wasn't Mez' blood but parsnip juice or horseradish sauce, you need to explain why Raff and Amanda dipped their feet in these substances to leave their incriminating evidence at the crime scene.
The discovery of Amanda Knox's DNA mixed with the victims DNA in a footprint with no useful characteristics that is presumed to have been made in blood is difficult to explain.[16]
Finally, how did the court reasonably decide the burglary was staged after the murder?
Rep 176 (L1 in the inspection report) was a Luminol trace found to have the victim's DNA, located on the floor near the window..[18] Rep 177 (L2) was between the door and the window, containing a Knox/Victim mixed profile.[19] That the victim's blood had been tracked into Filomena's room proved to the satisfaction of the courts that the staging must therefore have taken place after the murder.

You are demanding that criminal courts must have 100% scientific certainty. This has never been the case. The acid test has always been: Beyond a Reasonable Doubt.
In a serious crime such as this, the bar is very high, especially where young adults are involved.
Massei and Nencini were unable to get the kids below this high bar of reasonable doubt.
In other words, each satisfied itself the kids were guilty as charged and the evidence corroborated it.
