If the attack was motivated by the cameras, it would not be the first in the country in recent years.
Montgomery County, the first Maryland county to implement the cameras, has reported a series of incidents of vandalism affecting speed cameras or alerting drivers to their presence.
In 2007, a Tennessee man shot a speed camera when it snapped a photo of his speeding car. A year later, an Arizona driver repositioned traffic cameras in collision-prone intersections to alter their point of view.
In 2009, a speed-camera operator was fatally shot in Arizona by an angry driver who is now serving a 22-year sentence for murder.
AAA Mid-Atlantic spokesman John Townsend said the attack Wednesday was at the very least misguided because the camera was in a legitimate work zone.
“But it shows you how widespread the mistrust is becoming,” he said. “No one justifies an attack like this, but people are really upset about the cameras.”
