The National Security Agency has an Achilles heel, according to some anti-surveillance activists. The key vulnerability, according to members of the OffNow coalition of advocacy groups: The electronic spy agency’s reliance on local utilities.

The activists would like to turn off the water to the NSA’s $1.5 billion Utah Data Center in Bluffdale, Utah, and at other facilities around the country.

Dusting off the concept of “nullification,” which historically referred to state attempts to block federal law, the coalition plans to push state laws to prohibit local authorities from cooperating with the NSA.

Draft state-level legislation called the Fourth Amendment Protection Act would – in theory – forbid local governments from providing services to federal agencies that collect electronic data from Americans without a personalized warrant.

No Utah lawmaker has came forward to introduce the suggested legislation yet, but at least one legislator has committed to doing so, according to Mike Maharrey of the Tenth Amendment Center. He declined to identify the lawmaker before the bill is introduced.
