美国安局每年搜集全球2.5亿封电子邮件

U.S. officials say the documents show that intelligence collection programs that inadvertently intrude on Americans' privacy are found and fixed.

But they also appear to raise new questions about operations by the eavesdropping National Security Agency and its oversight by the secret U.S. Foreign Intelligence Surveillance Court (FISC).

"The court is troubled that the government's revelations regarding the NSA's acquisition of Internet transactions mark the third instance in less than three years in which the government has disclosed a substantial misrepresentation regarding the scope of a major collection program," Judge John Bates of the surveillance court wrote in one of the declassified documents.

More specifically, Bates said in an October 2011 ruling that the court had concluded that the process that resulted in improper collections of the tens of thousands of emails was "in some respects, deficient on statutory and constitutional grounds."

'NOT AN EGREGIOUS OVERREACHING'

The emails in question represent only a small slice of the electronic communications scooped up around the world by the NSA. It targets about 250 million email communications for collection each year and, under a separate program, has captured and kept records of millions of phone calls by Americans.

According to the documents, only about 9 percent of the emails - or less than 25 million - are collected from "upstream" sources, which officials familiar with intelligence operations said are cable links belonging to telecommunications companies.
