The idea of American troops invading Canada -- as satired by the late John Candy and his offensive-line mate director Michael Moore in the film "Canadian Bacon" -- was a concept too silly even for good satire.

The Posse Comitatus Act of 1878 generally prohibits the military from law enforcement activities within the United States. If armed officers are going to knock on Americans’ doors, or arrest them in the streets, they should answer to civilian authorities.
