With Congress on the verge of outlining new parameters for National Security Agency eavesdropping between suspicious foreigners and Americans, lawmakers are leaving largely untouched a host of government programs that critics say involves far more domestic surveillance than the wiretaps they sought to remedy.
These programs - most of them highly classified - are run by an alphabet soup of federal intelligence and law enforcement agencies. They sift, store and analyze the communications, spending habits and travel patterns of U.S. citizens, searching for suspicious activity.
The surveillance includes data-mining programs that allow the NSA and the FBI to sift through large databanks of e-mails, phone calls and other communications, not for selective information, but in search of suspicious patterns.
Other information, like routine bank transactions, is kept in databases similarly monitored by the Central Intelligence Agency.
"There's virtually no branch of the U.S. government that isn't in some way involved in monitoring or surveillance," said Matthew Aid, an intelligence historian and fellow at the National Security Archives at The George Washington University. "We're operating in a brave new world."
Federal rules limit the ways some of the information can be used and shared among government agencies. Pending changes to the Foreign Intelligence Surveillance Act contain numerous provisions set up to safeguard the privacy of Americans. But there are few similar protections with other types of surveillance.
Under the FISA proposal, for example, a CIA transcript or NSA summary of an innocent social conversation between a foreign terrorist and his relative in the United States would not be shared with other intelligence analysts. Even if the conversation was later found to have investigative merit, the U.S. relative's name and other identifying information would either be redacted or revealed only under limited circumstances to select agencies.
The Bush administration argues that the privacy and civil liberties protections in place for surveillance not covered by the FISA rules are "unprecedented." In addition to the data-mining, use of financial transaction databases and satellite imagery, the surveillance includes monitoring the travel patterns of airline passengers.
Use of satellites by local law enforcement agencies, for instance, is supposed to go through a stringent approval protocol at the Department of Homeland Security's newly formed National Applications Office.
