More than a year ago, the city announced that police would crack down on illegally parked cars and that resources would be diverted from writing speeding tickets to ticketing illegally parked cars.
Conclusion
The police chief's excuse — that resources had to be diverted from speeding tickets to drug-related crime — is not true.
Evidence
The chief said resources were diverted from speeding tickets to fight drugs. But speeding tickets are still being written at the same rate as ever.
Evaluate
For the author's reasoning to work, "as many speeding tickets as ever" has to be incompatible with "resources actually being diverted." If the police could keep writing the same number of tickets and divert resources to drugs at the same time, the chief's explanation could still be true.
Goal
The correct answer should establish that maintaining the same speeding-ticket output is incompatible with diverting resources to drugs.
