The vicious cycle described above could not happen unless which of the following is true ？（）

A. Shoplifters usually steal only items that they need but cannot afford.

B. Retailers do not take shoplifting losses into account when they initially set their prices.

C. The best way for retailers to address shoplifting is by punishing shoplifters to the tallest extent of the law.

D. Some people would shoplift no matter how low retailers set their prices.

E. It costs retailers more to pay security guards to prevent shoplifting than just to absorb the cost of occasional losses due to theft.
