Patriot Act Free Zones
From wired.com: In the past two years, more than 300 cities and four states have passed resolutions calling on Congress to repeal or change parts of the USA Patriot Act that, activists say, violate constitutional rights such as free speech and freedom from unreasonable search and seizure.
Barring that, the resolutions declare that their communities will uphold the constitutional rights of their residents should federal law enforcement agents come knocking on the door of local authorities for assistance in tracking residents. This means local authorities will insist on complying with federal orders only in ways that do not violate constitutional rights. The resolutions are not binding, however, and do not affect the federal government's actions.
