Traditionally, powerful spy satellites have been used to search for strategic threats overseas. But now the Department of Homeland Security has developed a new office to use the satellites to [monitor the US itself]. [DHS] officials ... faced extensive criticism [in Congress] about the privacy and civil liberty concerns of the new office, called the National Applications Office. [House Homeland Security] Committee members expressed concern about abuse of the satellite imagery, charging that Homeland Security had not informed the oversight committee about the program. What's most disturbing is learning about it from The Wall Street Journal," said Committee Chairman Rep. Bennie Thompson, D-Miss. The lawmakers also expressed concern about using military capabilities for U.S. law enforcement and Homeland Security operations, potentially a violation of the Posse Comitatus Act, which bars the military from serving as a law enforcement body within the United States. Committee members said that in addition to not being informed about the National Applications Office program, they had not yet been provided with documents defining the limits and legal guidance about the program. [They] sent a letter to Homeland Security saying, "We are so concerned that ... we are calling for a moratorium on the program. Today's testimony made clear that there is effectively no legal framework governing the domestic use of satellite imagery for the various purposes envisioned by the department."
