The Vomiter Speaks
The vomiter—or should I say, "vomiteer"—a student named Matthe Skomarovsky, defends his action in this letter to the Crimson. He points out that he vomited into a "double plastic bag," so no one had to pick up after him. And he argues that recruitment is not an act of free speech, and is therefore disruptable.
Neither of these arguments strikes me as suasive. On the aesthetics of vomiting, Skomarovsky should stick to his guns. If he feels so strongly about the ethics of CIA recruiting, he should insist that his actions were determined to shock and awe—not unlike a monk who sets himself on fire—and that the very point is to provoke people into having a visceral reaction.
On the second point...though I'm not a First Amendment lawyer, somehow I doubt that commercial speech—i.e., recruiting—is not protected by the Constitution.
