A study found that at intersections where red-light cameras were installed, accidents decreased by 28 percent over three years. Traffic officials concluded that the cameras are an effective deterrent against dangerous driving behavior.
Which one of the following, if true, most seriously weakens the argument?
- The expense of maintaining the cameras outstripped the revenue collected from the resulting traffic fines over the three years.
- At intersections without cameras, the number of accidents held steady or even ticked upward over the same period.
- A citywide safety push that added police patrols and lowered speed limits took effect at the very moment the cameras were installed.
- Many drivers ticketed by the cameras said they had no idea the cameras were there until the fine arrived by mail.
- The 28 percent reduction was the largest accident decline ever recorded at those particular intersections.
