cold fjord writes "Looks like last year was pretty busy. I wonder how many were leaks and media? From the Washington Post: 'The number of wiretaps secured in federal criminal investigations jumped 71 percent in 2012 over the previous year, according to newly released figures. Federal courts authorized 1,354 interception orders for wire, oral and electronic communications, up from 792 the previous year, ... There was a 5 percent increase in state and local use of wiretaps in the same period. ... There is no explanation of why the federal figures increased so much, and it is generally out of line with the number of wiretaps between 1997 and 2009, which averaged about 550 annually. There was also a large number of wiretaps in 2010, when 1,207 were secured. A single wiretap can sweep up thousands of communications. One 30-day local wiretap in California, for instance, generated 185,268 cellular telephone interceptions, of which 12 percent were incriminating, according to the report. The vast majority of the wiretaps in both federal and state cases were obtained as part of drug investigations, and they overwhelmingly were directed at cellphones ... Only 14 court orders were for personal residences. Most jurisdictions limit the period of surveillance to 30 days, but extensions can be obtained.'"
