“the First Amendment is understood as a general restriction on the government’s behavior, as The Volokh Conspiracy’s Ilya Somin points out.
“The First Amendment’s protection for freedom of speech, like most constitutional rights, is not limited to US citizens,” he writes. “The text of the First Amendment is worded as a general limitation on government power, not a form of special protection for a particular group of people, such as US citizens or permanent residents.”
Setting aside the constitutional issue, the detention of a student activist for engaging in what would clearly be considered First Amendment–protected activity under other circumstances is very alarming. If the State Department wishes to proceed with this course of action, the burden is on the government to sufficiently explain why Khalil should be deported. Authorities must persuasively demonstrate that his conduct crosses some very, very red line.
Yet, at present, the government’s justifications don’t come anywhere close to satisfying such a requirement. On the contrary, the official explanation for Khalil’s detention is so woefully insufficient as to be laughable—except, of course, this matter isn’t funny at all.”
