Every decade or so, the government makes the case for expanding its wartime powers and curtailing the citizenry’s freedom—in the war on terrorism, war on drugs, war on communism, war on foreigners, war on extremism, war on dissidents, war on peace activists, war on anti-government speech, etc.—all for the sake of national security, of course, and as expected, the American people fall in line. This time around, the government wants us to buy into the fiction that this war on illegal aliens is so necessary for national security that we should be grateful when roving bands of border patrol agents, flexing their muscles far beyond the nation’s borders, exercise their right to disregard the Constitution at every turn. Except these border patrol cops aren’t just disregarding the Constitution. They’re trampling all over the Constitution, especially the Fourth Amendment, which prohibits the government from carrying out egregious warrantless searches and seizures without probable cause.
