The Year is 1872

Louisiana officials order U.S. marshals away from the Colfax county courthouse, for fear that they might enforce federal law.  Compare to 8/3/17 Sacramento Bee:

California’s top labor law enforcer wants federal immigration agents to stay away from offices where state investigators weigh claims about underpaid employees and workplace retaliation.

Labor Commissioner Julie Su last month directed her staff to turn away Immigration and Customs Enforcement agents unless the federal officers have warrants.

Her directive followed three instances over the past 10 months in which immigration agents sought information about California workers who had filed claims against employers. In two cases, immigration agents attempted to attend hearings where investigators discuss claims with workers and their employers, Su said. In all three cases, the agents left when they were asked, she said.

Expulsion if not secession!  Even better: 8 USC 1324(a)(1)(A)(iii):

Any person who—knowing or in reckless disregard of the fact that an alien has come to, entered, or remains in the United States in violation of law, conceals, harbors, or shields from detection, or attempts to conceal, harbor, or shield from detection, such alien in any place, including any building or any means of transportation;

That's a felony.
