This below is the very definition of spying.
Data Mining. The FBI is
sweeping up incredible amounts of information about innocent Americans through unchecked data collection and data mining programs. According to documents obtained by
Wired magazine in 2009, an arm of the FBI called the National Security Branch Analysis Center (NSAC) has collected 1.5 billion records from public and private sources in a massive data mining operation. The records collected by the FBI include financial records from corporate databases, such as hotel and rental car company transactions; millions of "suspicious activity reports" from financial institutions; millions of records from commercial data aggregators; a multitude of law enforcement and non-law enforcement government databases; and public information gleaned from telephone books and news articles. The NSAC records include data from the FBI's
Investigative Data Warehouse, which was identified in a Department of Justice Inspector General
reports as the depository for information collected by the FBI through National Security Letters (NSLs) and illegal
exigent letters
