Here's a link to the new documentary 'Don't Tread on Me: Rise of the Republic'. It is about state sovereignty and the difference between a republic and a democracy. This is the legal path that must be taken to throw off a tyrannical gov't. All states should be drawing their own lines in the sand now.
The documentary makes crystal clear why Arizona's immigration law is nobody else's business but the citizens of Arizona, 71% of whom support the legislation.
It's about 1.5 hrs. long, but I highly recommend it to those who don't understand the line of authority from the citizen, to the state, to the federal gov't.
In a nutshell: The Tenth Amendment to the Constitution provides that State laws (that comply with the federal constitution) surpass federal laws.
