Federal prosecutors counted immigration violations, marriage fraud and drug trafficking among anti-terror cases in the four years after 9/11 even though no evidence linked them to terror activity, a Justice Department audit said Tuesday. Overall, nearly all of the terrorism-related statistics on investigations, referrals and cases examined by department Inspector General Glenn A. Fine were either diminished or inflated. Only two of 26 sets of department data reported between 2001 and 2005 were accurate, the audit found. It found that data from the Executive Office of U.S. Attorneys were the most severely flawed. Auditors said the office, which compiles statistics from the 94 federal prosecutors' districts nationwide, both under- and over-counted the number of terror-related cases during a four-year period. The numbers, used to monitor the department's progress in battling terrorists, are reported to Congress and the public and help, in part, shape the department's budget. Other examples, according to the audit, included: charges against a marriage-broker for being paid to arrange six fraudulent marriages between Tunisians and U.S. citizens, prosecution of a Mexican citizen who falsely identified himself as another person in a passport application, [and] charges against a suspect for dealing firearms without a license.
