"The Omnibus Crime Control and Safe Streets Act of 1968 requires the Administrative Office of the United States Courts (AO) to report to Congress the number and nature of federal and state applications for orders authorizing or approving the interception of wire, oral, or electronic communications. The statute requires that specific information be provided to the AO, including the offense(s) under investigation, the location of the intercept, the cost of the surveillance, and the number of arrests, trials, and convictions that directly result from the surveillance. This report covers intercepts concluded between January 1, 2002, and December 31, 2002, and provides supplementary information on arrests and convictions resulting from intercepts concluded in prior years. A total of 1,358 intercepts authorized by federal and state courts were completed in 2002, a drop of 9 percent compared to the number terminated in 2001. The number of applications for orders by federal authorities rose 2 percent to 497. Following an increase of 41 percent in 2001, the number of applications reported by state prosecuting officials dropped 14 percent in 2002. The average number of persons whose communications were intercepted increased 7 percent. The number of communications intercepted per order was 9 percent higher, and the number of incriminating communications reported per wiretap was 21 percent higher."
