I don't know enough about US extradition to know if the US Government would agree. My understanding is that Italy files paperwork. The Department of State or Department of Justice verifies that the necessary claims and documents are provided. With that, a federal authority would take Amanda into custody in the Seattle area and detain her at a federal facility in the Seattle area. An attorney for Amanda immediately files a writ of habeas corpus (it's already prepared, just in case) compelling the government to demonstrate to the federal court probable cause to arrest her.
At that point 100 journalists, TV crews, and Entertainment Tonight descend on Seattle, the White House, Department of State, Departmen of Justice, and the Italian Embassy in Washington. Bill Clinton speaks up. The federal court holds a hearing, at which point some very heavy hitter attorneys, backed by ex-FBI homicide investigators and profilers, a forensic engineer, DNA experts, a former State Court judge, extradition attorneys, challenge the detention on grounds of double jeopardy, human rights violations, physical abuse, psychological torture, use of Reid technique, etc.
Who knows, maybe a courageous retired Italian judge named Hellman might appear in Seattle as an expert witness to testify to the court that the Italian process is corrupted (that should be worth a movie, don't you think?). Maybe even the Grand Master of the Masons will appear? Maybe even Edgar Snowdon says the NSA has recordings of PLE's official and private phones detailing wrongdoing and a conspiracy to frame an innocent American.
Then Donald Trumph calls for a boycott of Italy and acbytesla cancels his order for the Lamborghini. And London John stops cooking pasta and dirtying his kitchen wall. And I threaten to cut my daughter's allowance if she even thinks of buying Prada. And ten percent of the American students preparing to study in Italy next semester decide they would rather go to Paris instead.
Then some Seattle people who are worth billions decide to fund the innocent project. And that movie is finally made. Starring Lindsey Lohan as Andrea Vogt. And Pussy Riot riots! Right before the next elections.
Then Mastercard rolls out the "Visit Italy" legal insuance credit card benefit, consisting of a wallet card in Italian asserting your legal rights and a silk hankie (made in China) printed with a map showing escape routes over the Alps to neutral Switzerland - and I get royalties.
Where was I?
I was going to LOL this... it is funny, really.
Except for Raffaele. And for the Kerchers. Someone printed something somewhere about some Italian politician denouncing the Mayor of Perugia (!) for not demanding Knox's immediate extradition to Italy to face trial. No one informed this politician that:
1) the Mayor of Perugia has no jurisdiction at all
2) that even Judge Nencini said that Knox was "lawfully abroad".
But the "Let's blame Knox for tooth decay" brigade seems to be intact in Italy, because this politician ostensibly chewed out Perugia's embattled mayor for not responding adequately to the fall in business and students for the town in the last 6 years; this fall apparently because the mayor had not blamed Amanda for it!!!!
Meanwhile, people like Gloria Allred (11 months ago on Piers Morgan) says she counsels people from abroad NOT to do business in Italy because of a legal climate where the transition to an adversarial system is incomplete, and legislation to move the judiciary in that direction is constantly frustrated - apparently it erodes the power of P.M.s and prosecutors; but this is now being more widely seen as creating an unstable climate in the whole country for doing business.
Maybe they can find a way of blaming Amanda Knox for that.
Me, I am sitting here listening to a virtual teenager say that she'd only responded to the police, who kept showing her a text on her own phone and demanding to know if she'd witnessed a murder.
In short - it was Ficarra who "brought Lumumba into the room" for this naive virtual-teenager to agree, once she "buckled", that he was the one she was confusedly imagining down the hall killing Meredith. (All the while telling them she'd never left Raffaele's, something even Judge Massei agrees was her consistent claim!)
And on THAT confused remembrance, of the meaning of a text message Ficarra kept throwing in this virtual teenager's face (after a couple of well placed "taps on the head"), they rush out and arrest a guy who had an iron-clad alibi.
And for this - 100 journalists, TV crews, Entertainment Tonight descend on Seattle, the White House, Department of State, Department of Justice, and the Italian Embassy in Washington. Bill Clinton speaks up - as if Hillary actually needs the 18-30 female demographic to be elected in 2016!!! - and John Douglas testifies as do top DNA experts... testifying to a US court, where all the Perugian-court sins, not to mention now Cassazione, are laid bare to.....
...... erode further confidence in Italy.
Whither Raffaele and the Kerchers? Rudy Guede can go to hell, the forgotten man in this, as he gets the education he deprived Meredith of.
