Slashdot linked up this article detailing (sort of) what is the first acknowledged "get" directly attributable to the NSA, one of the more secretive intelligence organizations in the US:
Citing anonymous sources in the British intelligence community, The Sunday Times reported that an e-mail message intercepted by NSA spies precipitated a massive investigation by intelligence officials in several countries that culminated in the arrest of nine men in Britain and one in suburban Orleans, Ont. -- 24-year-old software developer Mohammed Momin Khawaja, who has since been charged with facilitating a terrorist act and being part of a terrorist group.
Well, since the NSA monitors everything else, I guess I'll just say good job, and quit reading my e-mail!
