The 2014 OIG report is released with significant redactions. In a footnote, the OIG emphasizes that it believes the redactions are excessive, noting that the FBI's decision to assert that certain information is sensitive has "the effect of redacting information we believe is important to the public's understanding of the FBI's compliance with NSL requirements." The report finds that the FBI has complied with many of the OIG's recommendations, but that "additional effort from the FBI remains necessary to implement three recommendations we made in our previous reports to improve the FBI's record-keeping practices." The report also finds that the FBI issued fewer NSLs from 2007-2009, but returned to normal numbers after 2009. While the OIG notes improvement in some areas with regards to compliance with NSL requirements, it makes seven new recommendations to improve NSL practics. The report also notes significant issues with how the FBI interprets the scope of its authority under NSL statutes, as well as ongoing problems with the FBI's use of exigent letters, which are supposed to be used only in cases of emergency and have continued to raise concerns about constitutionality.
