That's not what the Constitution says.
The Federal government was given limited and enumerated powers. Under the Tenth Amendment, powers not granted to the Federal government are reserved to the States or the people.
In the case of Klamath, where does the Constitution, in your opinion, grant the power to the Feds to overrule local law enforcement?
To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States, and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings;
In addition, only THREE things are recognized by the Constitution as being crimes under general (that is, outside of the areas listed above) FedGov jurisdiction: Piracy, Treason and Counterfeiting. However, deporting illegals could come under their purview, I suppose. The rest of the things FedGov gets into are clearly unconstitutional. Thank God some local sheriffs are getting smart about that sort of thing.
