Police captain: The chief of police has indicated that gifts of cash or objects valued at more than $100 count as graft. However, I know with certainty that no officer in my precinct has ever taken such gifts, so the recent accusations of graft in my precinct are unfounded. The reasoning in the police captain's argument is most vulnerable to criticism on the grounds that the argument ['fails to consider that there may be other instances of graft besides those indicated by the chief of police', 'relies on a premise that contradicts the conclusion drawn in the argument', 'bases a claim about the actions of individuals on an appeal to the character of those individuals', 'takes for granted that if the accusations of graft are unfounded, so is any accusation of corruption']
