Hugh Pickens writes "The National Geospatial-Intelligence Agency, part of the Department of Defense, is using satellites to track the activities of drug cartels operating along the US-Mexican border. The agency is supplying photos to pinpoint Mexican narcotics operations and anticipate smuggling attempts into the United States. During a conference on border security held in Phoenix last week, Scott Zikmanis said his agency already has supplied some data to the El Paso Intelligence Center, a federal clearinghouse for investigating drug cartels. Any border-security surveillance will be done over Mexico, not the US says Zikmanis because a federal law, the Posse Comitatus Act, strictly limits US military operations on American soil unless such operations are authorized by Congress. Civil rights attorneys question the use of satellite technology in law enforcement. 'We are in the midst of a really dangerous time in terms of technology,' said Chris Calabrese, an attorney with the American Civil Liberties Union. 'The idea that such a powerful tool might be turned on US citizens is really troubling.'"
