Similar legislation has been introduced in 12 states. From Truthout.org:

On Tuesday, January 28th, a transpartisan group of four Vermont state representatives introduced legislation that would block some of the practical effects of mass data collection by the National Security Agency (NSA).

Rep. Teo Zagar (D-Windsor-4-1), along with co-sponsor Reps. Susan Davis (P/D-Orange-1), Patricia Komline (R-Bennington-Rutland) and William Stevens (I-Addison-Rutland) introduced the Fourth Amendment Protection Act to prohibit any state support of the NSA.

Based on model legislation drafted by the OffNow coalition, House Bill 732 (H732) would make it state policy to “refuse to provide material support for or assist or in any way participate in the collection of a person’s electronic data or metadata by any federal agency or pursuant to any federal law, rule, regulation, or order unless the data is collected pursuant to a warrant that particularly describes the persons, places, and things to be searched or seized.”

The bill would forbid Vermont from using information collected without a warrant by federal authorities, and bar the state from providing basic infrastructure, including water and electricity, to federal programs that participate in mass collection of data and metadata. Read more at Truthout.
