I have no problems with getting emails by a search warrant from an overseas server. Drug trafficking is global, so should the law enforcement be. I know, I am addressing this particular case, I am not saying "go" on a general basis. But I cases like this, with a search warrant, that turns up during an ongoing investigation, I really have no problem.

By the way, in Norway, blood samples are taken from murderers. 23% of all murderers had thc in their veins.
