Letter to the editor: I was shocked to learn that Judge Mosston was convicted of criminal assault, but I disagree with my fellow citizens who believe that he should be forced to resign. I have played cards with Judge Mosston for many years, and he has always shown himself to be fair toward me and our fellow cardplayers. Our judicial system simply cannot afford to lose any just and fair judges.
The reasoning in the letter is most vulnerable to the criticism that itThe writer concludes that Judge Mosston should not be forced to resign because he has behaved fairly while playing cards.
The flaw is that fairness in a private card game is weak evidence for
fairness or competence as a judge.
(A) confuses duties specific to legal professionals with the responsibilities of private citizens
Wrong. The argument does not confuse legal duties with private-citizen duties. It uses private behavior as evidence about professional suitability.
(B) insists upon a distinction between "fair" and "just" which cannot plausibly be maintained
Wrong. The argument does not depend on a distinction between “fair” and “just.”
(C) makes a general claim about an individual's professional competence based on an unrepresentative sampling of the individual's behavior
Correct. The writer judges Mosston’s fitness as a judge based on personal experience playing cards with him, which is not representative evidence of his judicial fairness or professional competence.
(D) treats the violent crime of criminal assault as if its consequences were no more serious than winning or losing at cards
Wrong. The writer may underweight the assault conviction, but the specific reasoning flaw is not that the crime is treated as equivalent to a card-game result.
(E) asserts a conclusion based on popular opinion rather than on argumentation
Wrong. The writer actually rejects popular opinion and gives an argument, though the argument is weak.
