I stopped reading after researching their first complaint, section 103. They claim the wiretaps could be done today, for up to 15 days. Wrong. Section 103 gives a 15 day window immediately after an attack or authorization of the use of force.
Under 50 U.S.C. §§ 1811, 1829 & 1844, the Attorney General may authorize, without the prior approval of the FISA Court, electronic surveillance, physical searches, or the use of pen registers for a period of 15 days following a congressional declaration of war. This wartime exception is unnecessarily narrow; it may be invoked only when Congress formally has declared war, a rare event in the nation’s history and something that has not occurred in more than sixty years. This provision would expand FISA’s wartime exception by allowing the wartime exception to be invoked after Congress authorizes the use of military force, or after the United States has suffered an attack creating an national emergency.
So in the chaos if we were attacked tomorrow, they’d have 15 days of relaxed rules. After that standard rules of warrants apply.
This is the problem with getting fringe group interpretations instead of reading the actual text of the law.
