If true, then this would certainly explain a lot. I do think though, that it is a bit of a strech to charge him with "ordering a criminal conspiracy". As we have been finding out, much had occured prior to the 1950s - hardly a time when Ratzinger was in a position to authorize and order a conspiracy.
Given the historical records of European countries and the Church, though, this doesn't surprise me. And, again, read what was said in the La Sallette apparition. This very same event sounds very similar to what was foretold. Also, I think that a simlar warrant was issued for the arrest of Archbishop Marcinkus over the Italian Bank scandal. I don't believe that he ever left the Vatican.
THAT being said, in a way, doesn't this present a "refreshing" precedent? Picture this....... Obama (or Bush, or any other president) has a bench warrant issued by a court in Brussels for their arrest the next time they step out fo the country, US assets seized overseas, accounts frozen, etc. Remember, the Pope is also a leader of a country (like it or not). So, this same tactic can (and most probably will) be used at some point in time against an American president for the actions of subordinates, and the inevitable cover-up. Two sayings spring immediately to mind: "Those in glass houses should throw stones", and, "Be careful what you wish for".
I know that a lot of people don't like Catholics, but this is one HECK of a precedent being set. I can picture a whole slew of cases being filed by Middle Eastern, African and Asian countries against the US.......
