You're starting to convince me, but I thought Curatolo and Capezzali were considered unreliable - Curatolo, "an alcoholic with mental health problems (probably)", and Capezzali, "old, a bit deaf (probably)". Or are they now considered reliable if they support the defence?
It's mostly a demonstration of how the dominoes fall once the initial domino of the time of death has been flicked over.
Once that domino falls then either Curatolo was lying/mistaken, or he gives Knox and Sollecito an alibi for the time of death. If he is lying/mistaken then the guilters who have been arguing strenuously that he should be regarded as a reliable witness, as well as Massei and Mignini, have a substantial amount of egg on their faces. If he gives Knox and Sollecito an alibi then the entire prosecution falls over on the spot.
Similarly once the TOD domino goes over then Nara with her magic ear is revealed as an old fantasist who also should never have been taken seriously, and once again Massei, Mignini and the on-line guilter community to adamantly defended her magic ear look rather silly.
With the Curatolo domino knocked down, the prosecution has zero time-sensitive evidence with which to try to break Knox and Sollecito's computer alibi as far as I am aware. Nobody else claims to have seen them out of the house, and none of the purported forensic evidence puts them at the house at the time of death.
The next domino that is trembling is the DNA evidence on the bra clasp and the knife. If it was indeed Meredith's DNA on the knife and Sollecito's on the bra clasp, but Sollecito and his knives were not present at the time Meredith was murdered, it follows that the DNA did not get there at the time of the attack. That leaves accidental contamination or deliberate falsification, and the guilters have argued forcefully that accidental contamination is impossible...
I am sure someone was telling me how bad it is to flip-flop over the same piece of data, in order to suit an argument...
You have misread other people's posts if you think this has ever happened.
If you read more closely, you will see that the arguments have been of the form "If A is true then Knox and Sollecito are innocent. Also, if A is not true then Knox and Sollecito are still innocent".
Anyway, I think you have cracked the case, it just needs the defence to call on you or Kevin Lowe, as expert witnesses, and the whole thing can be quickly cleared up. Did you get an invite yet?
Not this talking point again?
LondonJohn has explained the realities of court testimony from expert witnesses for you. I will assume that his explanation was satisfactory unless I hear further from you.
