Consider this hypothetical scenario: One reporter spreads it around town that your brother is beating the crap out of his wife. Though you have been aware of this situation for a very long time from other people who have told you about it, this reporter is soon discredited for hearing the rumor from an unreliable source.
What is the reasonable course of action?
(A) Ignore the reporter (he'll get reprimanded by-the-by), and then find the brother in order to beat the crap out of him and then turn him over to the police.
(B) Humiliate the reporter within and inch of his life, preach about integrity and what-not, and completely ignore the brother.
