There was an interesting exchange during a Senate Intelligence Committee hearing yesterday concerning the use of the Patriot Act’s §215 orders for business records and other tangible things. FBI Director Robert Mueller hinted that the orders may have been used to track purchases of hydrogen peroxide purchases in the investigation of aspiring bomber Najibullah Zazi, while Sen. Ron Wyden (D‑Oreg.) asserted that there is “a huge gap today between how you all are interpreting the PATRIOT Act and what the American people think the PATRIOT Act is all about and it’s going to need to be resolved.”
Let’s leave our curiosity about that by the wayside for the moment, though. I’m curious about one simple empirical claim Mueller made in his testimony: That the provision has been used over 380 times since 2001. I assume he’d know, but that seems inconsistent with what’s been publicly reported to date. It’s worth noting that there are actually minor discrepancies between the numbers provided in Congressional Research Service reports, audits from the Office of the Inspector General, and the Justice Department’s annual reports to Congress. But there are plenty of legitimate reasons these numbers might vary depending on how you count, and the total variance is a difference of about 17 orders total over the years.
We know from those Inspector General reports that the majority of those 215 orders issued were “combination” orders issued in tandem with another type of surveillance order called a “pen register” so that investigators could get subscriber information about the people whose communications patterns they were tracking. When Congress amended the Patriot Act in 2006, it built that authority right into the pen register statute, making it unnecessary to seek those “combination” orders. Prior to the amendment, the government got 173 of those “combination” orders. “Pure” 215 orders, which are now the only type needed, have been used much more sparingly. None were issued at all until 2004, and from 2004 through 2009 (depending on whose tally you want to use) there were between 75 and 92 orders issued (for an average of 12–15 annually since 2004). Throw in the combination orders and the upper-bound number through the end of 2009 is 265 orders.
