Critical Reasoning

165. The cities with the densest population have the highest ratio of police officers to citizens. Such cities also have the lowest rates of property crime without contact between perpetrator and victim. Thus maintaining a high ratio of police officers to citizens can serve as an effective deterrent to at least certain kinds of property crime.

Which of the following, if true, most seriously weakens the argument above?
(A) The quality of training that police receive varies from city to city.
(B) High population density itself makes it difficult to commit a property crime that involves no contact between perpetrator and victim.
(C) Many nonviolent crimes in large cities are drug-related.
(D) A majority of the perpetrators of property crimes in densely populated cities are not apprehended by the police.
(E) Property crimes without contact between perpetrator and victim represent only a small proportion of overall crime.
