As I reported earlier, during the hearing on the reauthorization of the PATRIOT Act today, DiFi said that the investigation against Najibullah Zazi is the biggest investigation since 9/11. She connected changes she had made in the proposed bill’s language about Section 215 Orders (which allow investigators to get any tangible thing from a third party, but which is generally used for business records) with that investigation. I will review the language she’s advocating tomorrow–it is actually worse than the existing language (here’s a good post on DiFi’s changes that’ll give you an idea of where I’m going). But the main point is she’s insisting that investigators be able to use Section 215 even to get information on people with no known tie to terrorism.

In an effort to understand what authorities the FBI is using for this investigation–particularly how it is using Section 215–I thought I’d list all the evidence included in Zazi’s detention motion, along with any comments made about how that evidence was collected. As you can see from the list below, a lot of this investigation relied on information that could be collected via a Section 215 order–particularly the purchase information on Triacetone Triperoxide (TATP) ingredients, but also the hotel records. Perhaps most interesting is the discussion of the three people "associated with Zazi" who bought TATP ingredients bolded in the list below; the source of this evidence is not disclosed.

Evidence Zazi searched "a beauty salon website" for hydrocide and peroxide (the source of this is not specified but it appears in the same paragraph as the discussion of the "lawfully authorized search")

Evidence that "individuals associated with Zazi purchased unusual quantities of hydrogen and acetone products in July, August, and September 2009 from three different beauty supply stores in and around Aurora;" these purchases include:

  • Person one: a one-gallon container of a product containing 20% hydrogen peroxide and an 8-oz bottle of acetone
