Emails obtained under legal court order (Score 1)

The real news here is that the emails were gathered under a legal court order.
As reported by Glen Greenwald http://www.salon.com/opinion/greenwald/2009/09/08/law/index.html the surveillance in question was entirely legal, conducted by obtaining warrants under the supervision of the FISA court where required by law. The disruption of that Terrorist plot thus proved exactly the opposite of what was widely claimed: namely, the extremely broad parameters of FISA easily allowed surveillance of dangerous Terrorists, and there was therefore no need to break the law as Bush officials did. But because the distinction between "legal" and "illegal" is no longer recognized when it comes to government acts, that fact eluded virtually all discussions of the British airplane plot. To prove that "legal surveillance is good" was to prove that "Bush's illegal eavesdropping was justified."
