Whistleblower: "NSA is capable of ...vacuum-cleaner surveillance"

Based on my understanding of the connections and equipment at issue, it appears the NSA is capable of conducting what amounts to vacuum-cleaner surveillance of all the data crossing the internet -- whether that be peoples' e-mail, web surfing or any other data.
Given the public debate about the constitutionality of the Bush administration's spying on U.S. citizens without obtaining a FISA warrant, I think it is critical that this information be brought out into the open, and that the American people be told the truth about the extent of the administration's warrantless surveillance practices, particularly as it relates to the internet.
Despite what we are hearing, and considering the public track record of this administration, I simply do not believe their claims that the NSA's spying program is really limited to foreign communications or is otherwise consistent with the NSA's charter or with FISA. And unlike the controversy over targeted wiretaps of individuals' phone calls, this potential spying appears to be applied wholesale to all sorts of internet communications of countless citizens.
