A Department of Justice Audit Report from March 2006 described Red Hook as "a system to collect voice and data calls and then process and display the intercepted information in the absence of a CALEA solution." The redacted report can be found online

The Electronic Frontier Foundation has obtained documents regarding Red Hook and DSC-3000 through their FOIA Litigation on documents relating to electronic surveillance systems. http://www.eff.org/flag/061708CKK/

Wired Magazine published an article on these systems, citing the EFF documents, on August 29, 2007. http://www.wired.com/politics/security/news/2007/08/wiretap
