OK, but this doesn't actually answer the question. Legally, after the annulment of the acquittal, Knox/Sollecito were considered convicted murderers (I think). Shouldn't they have been arrested and jailed? Even if their legal status was in some weird purgatory between accused and convicted, they were still more deserving of imprisonment than the months they spent in jail before they were charged, let alone on trial before the first verdict.
My question actually goes to a suspicion I have that the judiciary is well aware of the weakness of its case (and may even view Sollecito as collateral damage in a witch hunt which has mutated into a face-saving exercise). I simply see no other excuse for Sollecito being out of jail right now.
To my way of thinking, this is the one thing that the Nencini court got right.
Knox and Sollecito were in prison for their 2009 trial, not because of guilt or innocence, but that in 2008, Judge Micheli ordered them held in "precautionary detention". The three grounds for this are if they are a flight risk, if they are likely to reoffend, or if they are likely to tamper with evidence.
After the 2009 conviction, Sollecito and Knox were not re-imprisoned because of the Massei conviction, they were returned because the "detention order" still stood.
In Oct 2011 when Judge Hellmann decalred them to be factually innocent, he also quashed the detention order. (He actually was not required to do that!)
But Knox and Sollecito were released.
Ok - up to 2014. When Nencini re-convicted them, all of this is (as explained by others) pending the confirmation by Cassazione, the Italian Supreme Court which gives the final ruling on all criminal cases.
Nencini ordered Sollecito's passport revoked, but, here's the kicker, said that Knox was "lawfully abroad". He did not order their detention, because (apparently) they are not a flight risk, nor likely to reoffend, nor will they tamper with (nonexistent) evidence.
Sollecito was actually in Austria when he heard he'd been reconvicted. He then returned to Italy across the border and spent the night in a villa. The police arrived the next morning to seize his passport and travel documents.
Tabloids and guilters are saying he was "caught trying to leave Italy." The opposite is true. I mean, who when trying to flee the country stops and registers for the night
in the very last villa in the country!
But they are not imprisoned (or an extradition sought) before Cassazione signs off on the lower courts conviction. Their imprisonment in the meantime is by request of the prosecution and by order of a judge on precautionary grounds.
For instance, when Mignini was charged with a crime, obstruction of justice in the Narducci affair, he was free and actually prosecuting the case against these two while he, himself, could have been in prison. I mean, what are the chances that a prosecutor will tamper with evidence, when illegal wiretapping is his suspected crime!
