Argument X Would Get A Law Student a Failing Grade. What is X?
It’s common, when attacking a lawyer’s arguments, to say that such arguments would earn a law student a failing grade. See, e.g, Yoo, John, attacks on. Whatever the merits of the underlying attack, that particular claim is surely false, and shows the author either not to be a lawyer, or not to have gone to law school anytime in the last twenty years.
To be clear: to fail a law school class, your arguments have to be worse than merely bad, tending to lead to evil outcomes, and self-aggrandizing. They have to be so incomprehensible that they’re quite literally incoherent.
