The June 10 Metro article “Revenue from speed cameras in Md. falling” made no mention of any improvement in safety statistics, which was Maryland officials’ primary justification for installing cameras.

At one appeals court hearing, no fewer than 12 percent of the appellants were protesting cameras at the same two sites — on Germantown Road next to Darnestown Road and east toward Seneca Road. The official justification is a nearby private school, but that school does not generate any pedestrian traffic, which is the main reason schools merit special consideration. In fact, there is no pedestrian traffic on these country roads, which are lightly traveled during most of the day. It is not surprising that all these appeals were dismissed, though it helps explain why some drivers support cameras in areas where they are needed but have a strong reaction to being punished for perfectly safe driving in such locations.
