DeBlowHole is a premium jerk. However, these excerpts don’t prove that. They merely demonstrate that the people who work for him can’t do their jobs right. The fact that they leaked these means those same people can’t acknowledge their failings.
I agree. The only problem I see is that De Blasio failed to identify the particular person to hold accountable. Responsibility that is divided results in no responsibility at all.
One might wonder, however, how one is to identify "challenging words". A responsible underling would seek clarification.
