Total Number of Wiretaps for Drug Offenses in the US, 2013
"Drug offenses were the most prevalent type of criminal offense investigated using wiretaps. Table 3 indicates that 87 percent of all applications for intercepts (3,115 wiretaps) in 2013 cited illegal drugs as the most serious offense under investigation. 'Other major offenses,' a category that includes smuggling and money laundering, was the second-largest category and was specified as the most serious offense in approximately 4 percent of applications. Homicide, the third-most frequently cited crime, was specified in less than 4 percent of applications. Many applications for court orders revealed that multiple criminal offenses were under investigation, but Table 3 includes only the most serious criminal offense listed on an application."
