The Ignorance Defense
Confession: All these widely acclaimed leaders of multi-billion-dollar organizations like JPMorganChase, the IRS, and the NFL continue to impress me (in a disturbing, watching-a-catastrophe-happen way) with the unwavering strength of their audacity to use "I didn't know." and "No one told me." to shield themselves from being held accountable for the catastrophic fallout of their leadership failures.
BATAF: Voltaire was wrong: with great power comes no accountability.
