Nothing prevents your Elected County Sheriff from “Withdrawing Consent” for Federal Agents to operate within their County, or just Arresting Them.

Nothing except the Supremacy Clause of the Constitution and the U.S. Army.

Nothing except the Supremacy Clause of the Constitution and the U.S. Army.

The 10th Amendment came after the Supremacy Clause. If there is a conflict between the 10th Amendment and the Supremacy clause, the 10th Amendment takes precedence.

“Nothing except the Supremacy Clause of the Constitution and the U.S. Army.”

WARNING!! Graphic video of dictator tortured and killed.
