"'This report covers intercepts concluded between January 1, 2014, and December 31, 2014, and provides supplementary information on arrests and convictions resulting from intercepts concluded in prior years.' […] The number of federal and state wiretaps reported in 2014 decreased 1 percent from 2013. A total of 3,554 wiretaps were reported as authorized in 2014, with 1,279 authorized by federal judges and 2,275 authorized by state judges. Compared to the applications approved during 2013, the number approved by federal judges decreased 13 percent in 2014, and the number approved by state judges increased 8 percent. One state wiretap application was denied in 2014. In 25 states, a total of 141 separate local jurisdictions (including counties, cities, and judicial districts) reported wiretap applications for 2014. Applications in California accounted for 43 percent of all applications approved by state judges. Seventy-eight federal jurisdictions submitted reports for 2014. The District of Arizona authorized the most federal wiretaps, approximately 7 percent of the applications approved by federal judges. Federal judges and state judges authorized 962 wiretaps and 119 wiretaps, respectively, for which the AO [area of operations] received no corresponding data from prosecuting officials. Wiretap Tables A-1 and B-1 contain information from all judge and prosecutor reports submitted for 2014. The entry 'NP' (no prosecutor's report) appears in these tables whenever a prosecutor's report was not submitted. Some of the prosecutors' reports were received too late to include in this document, and some prosecutors may have delayed filing reports to avoid jeopardizing ongoing investigations. Information about these wiretaps should appear in future reports."
