Nationally, the number of wire, oral, or electronic communication interceptions in 2011 fell 14% from 2010 levels. This followed a 34% increase from 2009 to 2010. Wiretaps operated an average of 43 days. A wiretap order, on average, intercepted communications from 113 people, with 23% of communications considered incriminating.
This and other information about wiretaps is available in a report by the Administrative Office of the United States Courts. Federal law requires this office to collect information from federal and state officials, although only 25 states provided information and thus it appears that the state data is incomplete.
