A few days ago CNN host Piers Morgan got into it with the head of a gun-rights group. Now more than 87,000 people have signed an online petition demanding that Morgan, who is British, be deported for his "hostile attack against the U.S. Constitution." But the First Amendment does not exempt British nationals, which means those signing the petition are also committing a hostile attack against the Constitution. The irony is probably lost on them, says A. Barton Hinkle.
