Re: They dont want to use the MLAT.
I don't believe it's illegal, because the backlash could be even worse. I think it's more a child-like behaviour, they have seen an easy shortcut, and they want to make it available through a precedent, and like children, they can't understand the consequences.
I really hope it the case goes to the Supreme Court, the EU weighs in and warns of the consequences if US thinks they can freely investigate or spy foreign citizens on foreign soil only because they happen to use some US technology. Ms. Merkel is right - we can't trust US anymore.
