PEEKABOO Sure, the government's been eavesdropping on Americans in violation of the law. But at least the program's been restricted to international calls:

Q Can you assure us that all of these [NSA wiretapping] intercepts had an international component and that at no time were any of the intercepts purely domestic?

[Principal Deputy Director for National Intelligence] GENERAL [Michael] HAYDEN: The authorization given to NSA by the President requires that one end of these communications has to be outside the United States. I can assure you, by the physics of the intercept, by how we actually conduct our activities, that one end of these communications are always outside the United States of America.

That, at least, was the story:

A surveillance program approved by President Bush to conduct eavesdropping without warrants has captured what are purely domestic communications in some cases, despite a requirement by the White House that one end of the intercepted conversations take place on foreign soil, officials say.

Oops.
