@evacide My reading and understanding of this, is that the Swiss govt order came from an MLAT request from the FBI, and not a US court warrant. Thus, the issue, to me, is how US law enforcement essentially uses MLAT to bypass what in the US could be withheld without an appropriate judicial review. Maybe I’m projecting a misunderstanding, but when I had to respond to such requests, in the ISP I ran, we would, generally, only comply with a legal warrant or order authorized by a court.
