PBS Frontline-Spying On The Home Front

So many people in America think this does not affect them. They've been convinced that these programs are only targeted at suspected terrorists. à I think that's wrong. à Our programs are not perfect, and it is inevitable that totally innocent Americans are going to be affected by these programs," former CIA Assistant General Counsel Suzanne Spaulding tells FRONTLINE correspondent Hedrick Smith in Spying on the Home Front.

9/11 has indelibly altered America in ways that people are now starting to earnestly question: not only perpetual orange alerts, barricades and body frisks at the airport, but greater government scrutiny of people's records and electronic surveillance of their communications. The watershed, officials tell FRONTLINE, was the government's shift after 9/11 to a strategy of pre-emption at home -- not just prosecuting terrorists for breaking the law, but trying to find and stop them before they strike.

President Bush described his anti-terrorist measures as narrow and targeted, but a FRONTLINE investigation has found that the National Security Agency (NSA) has engaged in wiretapping and sifting Internet communications of millions of Americans; the FBI conducted a data sweep on 250,000 Las Vegas vacationers, and along with more than 50 other agencies, they are mining commercial-sector data banks to an unprecedented degree.
