The FBI uses NSLs to compel internet service providers, libraries, banks, and credit reporting companies to turn over sensitive information about their customers and patrons. Using this data, the government can compile vast dossiers about innocent people. Government reports confirm that upwards of 50,000 of these secret record demands go out each year. In response to an ACLU lawsuit (Doe v. Holder), the Second Circuit Court of Appeal struck down as unconstitutional the part of the NSL law that gives the FBI the power to prohibit NSL recipients from telling anyone that the government has secretly requested customer Internet records.

The other provisions the ACLU complains of:

• Material Support Statute. This provision criminalizes providing "material support" to terrorists, defined as providing any tangible or intangible good, service or advice to a terrorist or designated group. As amended by the Patriot Act and other laws since September 11, this section criminalizes a wide array of activities, regardless of whether they actually or intentionally further terrorist goals or organizations. Federal courts have struck portions of the statute as unconstitutional and a number of cases have been dismissed or ended in mistrial.

• FISA Amendments Act of 2008. This past summer, Congress passed a law to permit the government to conduct warrantless and suspicion-less dragnet collection of U.S. residents' international telephone calls and e-mails. This too must be amended to provide meaningful privacy protections and judicial oversight of the government's intrusive surveillance power.
