The Methods Used in the Zazi Investigation
I’ve been focusing on how Section 215 of the PATRIOT Act may have been used to investigate Najibullah Zazi, but Dina Temple-Raston had a great story yesterday cataloging the range of techniques (though she doesn’t name Section 215 specifically).
Intelligence Tip
I’ve seen a number of vague suggestions for when investigators first focused on Zazi. While she doesn’t describe it as the first thing that made investigators focus on Zazi, Temple-Raston does reveal that Pakistani intelligence gave the US information about Zazi’s actions in Pakistan.
Sources say officials acted after Pakistani intelligence allegedly told them that Zazi had met with al-Qaida operatives there.
From the context, it appears the US may have gotten this tip shortly after Zazi returned to the US in January.
FISA Roving Wiretap
From there, it appears the FBI applied for an got a roving FISA wiretap. Temple-Raston provides a detailed explanation of what a FISA wiretap is, noting that it can be used for emails as well (remember that investigators had identified three email addresses Zazi used).
In his case, officials tell NPR they asked a judge for what’s called a roving FISA wire tap.

Law enforcement officials close to the Zazi case tell NPR that the FBI applied to a special court for the wiretap months ago.
And note, since they already had intelligence from the Pakistanis, it would presumably have been easy to justify a traditional FISA warrant–not to mention establish reasonable cause for any of the other FISA or PATRIOT Act tools in question.
Physical surveillance
After they got contacts from Zazi about developing bombs (perhaps in July or August?), it appears they started tracking Zazi more closely. The FBI followed Zazi all the way from Denver to NY–and staged a drug stop on the George Washington Bridge.
FBI agents followed him on the 27-hour drive. And, just to make sure they tracked Zazi closely, they asked local law enforcement for help along the way. Zazi was pulled over several times for speeding. He apparently got a ticket in Kentucky. And the FBI knew about it.
When Zazi neared New York City on Sept. 10, the New York police pulled him over on the George Washington Bridge. Officials familiar with the case tell NPR that was an orchestrated operation between the FBI and NYPD. They wanted to make sure there weren’t any chemicals or a bomb in Zazi’s car. They told Zazi it was a routine search and, just to underscore the point, pulled over other cars on the bridge as well.
