From the good folks at EPIC:
In a Freedom of Information Act lawsuit, EPIC has obtained reports that detail the number of times the Surveillance Court authorized the use of techniques that gather the telephone numbers and metadata of phone customers and Internet users. The previously secret reports obtained by EPIC cover the period between 2000 and 2013. The reports reveal a dramatic increase in the use of these techniques in 2004 and then a significant reduction in 2008, likely the consequence of a shift to other investigative techniques. The documents show that nearly all applications to the Surveillance Court were approved without modifications. In 2013, EPIC petitioned the Supreme Court to end the bulk telephone record collection program. Former members of the Church Committee and dozens of legal scholars supported the EPIC petition.
