welcome to DU, MrDale ...
here's an excellent write-up on the FISA law by the Electronic Frontier Foundation's (EFF) Senior Counsel:
http://www.eff.org/Censorship/Terrorism_militias/fisa_faq.htmlbush said: ""I authorized the National Security Agency, consistent with U.S. law and the Constitution, to intercept the international communications of people with known links to al Qaeda and related terrorist organizations."
the FISA law would NOT allow this spying to occur on "US persons" (i.e. US citizens and permanent resident aliens) without "probable cause" being established by a US court.
If the target is a "U.S. person," which includes permanent resident aliens and associations and corporations substantially composed of U.S. citizens or permanent resident aliens, 50 U.S.C.A. § 1801(i), there must be probable cause to believe that the U.S. person's activities "may" or "are about to" involve a violation of the criminal statutes of the United States.
the person you are arguing with wrote:
Since the folks who were LEGALLY wiretappe within the US got identified through intelligence developed through captures of al-Qaeda agents and their equipment, it seems rather unlikely that they had contacts with many US-born American citizens. Most AQ assets enter countries on student visas -- which does not qualify them as a US person under FISA and therefore does not extend them the protection of warrants prior to or during surveillance.
first of all, the person is ASSUMING no "US persons" were spied on ... there is no basis provided to support this assumption ...
bush specifically said that those spied on were "people with known links to al Qaeda and related terrorist organizations" ... that is NOT an adequate standard to violate the fourth amendment rights of US persons ... to spy on US persons, bush would have had to establish "probably cause" in a US court ...
republicans spend a lot of time whining about courts that "legislate from the bench" ... funny how when the President violates the Constitutional rights of US citizens they don't seem at all concerned ... the FISA law provides very clear and specific rules for "domestic spying" ... bush doesn't get to decide when he can violate those rules ...
