Mirror servers

A legal regime in which U.S. citizens' data receives different levels of privacy and oversight, depending on whether it is collected inside or outside U.S. borders, may have made sense when most communications by U.S. persons stayed inside the United States. But today, U.S. communications increasingly travel across U.S. borders—or are (((stored))) beyond them. For example, the Google and Yahoo e-mail systems rely on networks of (((mirror))) servers located throughout the world. An e-mail from New York to New Jersey is likely to wind up on servers in Brazil, Japan and Britain. The same is true for most purely domestic communications.

In other words, [Executive Order 12,333] is a loophole in Americans' right to privacy: so long as the NSA is targeting foreigners abroad, it can sweep up Americans' communications, too.
