Here is a story about national security surveillance that probably won't get the attention it deserves:

  The three men convicted in the United Kingdom on Monday of a plot to bomb several transcontinental flights were prosecuted in part using crucial e-mail correspondences intercepted by the U.S. National Security Agency, according to Britain's Channel 4.
  The e-mails, several of which have been reprinted by the BBC and other publications, contained coded messages, according to prosecutors. They were intercepted by the NSA in 2006 but were not included in evidence introduced in a first trial against the three last year.
  That trial resulted in the men being convicted of conspiracy to commit murder; but a jury was not convinced that they had planned to use soft drink bottles filled with liquid explosives to blow up seven trans-Atlantic planes — the charge for which they were convicted this week in a second trial.
  According to Channel 4, the NSA had previously shown the e-mails to their British counterparts, but refused to let prosecutors use the evidence in the first trial, because the agency didn't want to tip off an alleged accomplice in Pakistan named Rashid Rauf that his e-mail was being monitored. U.S. intelligence agents said Rauf was Al Qaeda's director of European operations at the time and that the bomb plot was being directed by Rauf and others in Pakistan.
  The NSA later changed its mind and allowed the evidence to be introduced in the second trial, which was crucial to getting the jury conviction. Channel 4 suggests the NSA's change of mind occurred after Rauf, a Briton born of Pakistani parents, was said to be killed last year by a U.S. drone missile that struck a house where he was staying in northern Pakistan.

Fascinating. The BBC has the text of the intercepts here.
