(EN) Ryan Singel, FBI E-Mail Shows Rift Over Warrantless Phone Record Grabs, su Wired, 9 dicembre 2007.
«DCS 3000 – the FBI's tool for recording the phone numbers a target calls, or is called from – was set loose on 5,300 phones in 2005, at a cost of $320 per targeted number. Those costs did not include payments to telecoms for the intercepts. The software is maintained by Booz Allen Hamilton and contained more than 490,000 lines of code as of 2005.»
