Critical Reasoning

News commentator: "Our police commissioner announced a plan to dismantle manned surveillance video cameras throughout the city, because most man-hours spent observing them end up wasted because no crimes occur there. Most residents now have cell phones or access to public phones, so video cameras are no longer needed, says the police commissioner. However, the biggest risk of crime is in the Warehouse District, where there are not many residents or public phones, so some video cameras are still needed."

Which of the following, if true, most seriously weakens the argument?
A. It costs over five million dollars annually for the city to pay policemen to monitor video cameras.
B. Warehouses have automatic motion-detecting video cameras, which send an alarm to the police department.
C. Due to most video cameras' limited scope and quality, the police will receive less information from video cameras than from phone calls.
D. The police department is much nearer to residential areas than to the warehouse areas.
E. An average of one in five public phones does not work.
