Data: “Decline in Prosecutions for National Internal Security and Terrorism”

From TRAC:

Criminal prosecutions in the area of national internal security and terrorism have declined steadily since FY 2002, but are still significantly higher than pre-9/11 levels. The latest available data from the Justice Department show that during the first eight months of FY 2014 the government reported 128 new national internal security/terrorism prosecutions. If this activity continues at the same pace, the annual total of prosecutions will be 192 for this fiscal year. According to the case-by-case information analyzed by the Transactional Records Access Clearinghouse (TRAC), this estimate is down 28.6 percent over the past fiscal year when the number of prosecutions totaled 269, and has fallen 84.1 percent since the peak of 1,208 reached in FY 2002.
