At the end of 2006, the FBI's Telecommunications Intercept and Collection Technology Unit compiled an end-of-the-year report touting its accomplishments to management, a report that was recently unearthed via an open government request from the Electronic Frontier Foundation. Strikingly, the report said that the FBI's software for recording telephone surveillance of suspected spies and terrorists intercepted 27,728,675 sessions. Twenty-seven million is a staggering number given that the FBI only got 2,176 FISA court orders in 2006 from a secret spy court using the Foreign Intelligence Surveillance Act.

FBI agents illegally videotaped suspects, intercepted e-mails without court permission and recorded the wrong phone conversations during sensitive terrorism and espionage investigations, according to an internal memorandum detailing serious lapses inside the FBI more than a year before the Sept. 11 attacks.
wake up.
Of note is that the software at issue, the DCS-5000 gets information from carriers after they turn on surveillance on their switches once they get a court order (CALEA mandates the switches be wiretap-compliant). That means this number ostensibly has nothing to do with the government's secret warrantless wiretapping program, or the government's data-mining of billions of call records.
Your other link was about mistakes made in 2000, before current practices, before 911, and before the current Administration was even in power.
That's a hell of a lot of "potential terrorist" activity. Either that, or a lot of indiscriminate spying on US citizens by the Executive branch. Makes Hillary Clinton's 900+ FBI files look positively amateur by comparison.
