“INTERPOL can operate in the US and is not bound by the US Constitution.”
Interpol is not an elite fighting force about to invade South Carolina and round up gunowners coast to coast.
Interpol is a bunch of fat bureaucrats sitting in Europe who shuffle papers and surf the net. The idea of confronting well-armed hunters and combat vets in the American hinterlands would horrify Interpol bureaucrats.
1) The Council of Governors would control the National Guard which, theoretically, would be in a position to confront well-armed hunters.
2) The Stability Police Force would go house to house in pacified areas, acting like a SWAT team, and round up people for questioning.
3) Interpol is in charge of "rendition centers" where prisoners are taken and forced to confess. No Constitutional rights for folks at those locations.
If you think about what Obama has put in place, he's got control of military forces, law forces, and legal forces. This can be quite an effective infrastructure.
