In response to Brian Leiter.
Yoo is a legal professional with responsibilities in the public sphere beyond the groves of academe. A professor of structural engineering cannot lose tenure after a bridge collapse but he can lose his right to design bridges, at which point he can be fired. A lawyer like an engineer or a doctor is often not only a scholar, but a licensed practitioner. He can lose his license
Simple.
Leiter wants the benefits of "technical" professionalism but not the risks.
