” I learned the County Sheriff, unless otherwise provide by an amendment, has complete legal power in the County he’s elected to.”
Goes farther than that. Sheriff Mack in Arizona (I believe) sued the federal government and the USSC ruled in 1997 that the feds cannot require local officials to carry out the mandates of federal law. During Katrina, a couple of sheriffs posted armed guards to keep the FEMA gun grabbers out of their counties.
Another federal judge in Utah ruled that county commissioners and Indian tribes can pass specific laws nullifying regulations imposed by the federal
fascist bureaucracies.
Sheriff Mack is correct. He wrote a little book about it. It's worth reading: The County Sheriff--America's Last Hope.
