There are some Creator-endowed, unalienable rights (Life liberty and property) mentioned in the Bill of Rights, and there are some rights that are granted by Man. I don't think God said anything about the right to a Grand Jury, or a search warrant. It's not going to kill ZM, if his computer gets searched, and 3000 lives are saved as a result. And since he was a foreigner, it could have been searched without a warrant.
