More than 2,370 applications for wiretaps were filed and granted last year in state and federal courts across the country, marking a 26 percent increase above the previous year, according to a report issued Friday by the Administrative Office of the U.S. Courts.

The report, which captures applications filed between January and December last year, shows that 86 percent of all wiretap applications targeted drug crimes. Homicide cases were the second most frequently cited crimes.
