The following is a list of possible locations of NSA domestic interception points inside the United States. The list was presented by computer security researcher Jacob Appelbaum at a recent event held at the Whitney Museum in New York along with filmmaker Laura Poitras and ex-NSA employee William Binney. One of the addresses, an AT&T building on Folsom Street in San Francisco, is the location of Room 641A which was the subject of multiple lawsuits regarding the warrantless surveillance of U.S. citizens. A recent article in Wired quoted Binney as estimating that there are likely ten to twenty of these locations around the country.
