The above videos demonstrates that Sheriff Mack is not the only sheriff who has stood up to the Federal Government. This is a great example of how the Constitution is supposed to work. It shows that no one has special authority outside what is delegated by the People. Any law, policy, or judgment which violates the Constitution is null and void. It is the duty of all the People to refuse to obey unlawful orders. You might think that this idea would cause violence and the loss of the protections afforded by the government. But as the above videos show, a cool-headed sheriff, acting according to the Constitution, actually diffused such a potential crisis.
The 4th Amendment says,

No person shall be held to answer for a capital or otherwise infamous crime unless on a presentment or indictment of a grand jury, except in cases arising in the land or naval forces, or in the militia, when in actual service in time of war or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property without due process of law; nor shall private property be taken for public use without just compensation.
