 The top 50 plots were identified by NYU's Center for Law and Security based on, in sum, a number of factors including the seriousness of the crime, the importance of legal issues involved, and the amount of media attention received. See New York University School of Law, Center on Law and Security, "Terrorist Trial Report Card: September 11, 2001 - September 11, 2010," (undated) http://www.lawandsecurity.org/Portals/0/documents/01_TTRC2010Final1.pdf (accessed December 27, 2011). The 50 terrorism plots often included more than one defendant but the data used here was obtained by extracting, from the raw data of the cases comprising the top 50 plots supplied by New York University School of Law, Center on Law and Security, information on the main defendants in each plot.
 For the four detainees transferred from initial military detention into the federal system, the date of transfer was used as the date of arrest.
 The analysis presented here takes the raw data for the top 50 plots supplied by New York University School of Law, Center on Law and Security, extracts information from the cases of the main defendants in each plot, and combines that with information obtained from the Department of Justice and independent research on arrest and conviction dates conducted for Human Rights Watch with the special assistance of Trent Buatte and Abigail Gellman. It includes data from the cases of 91 different defendants.
