ROCKVILLE, Md. - No matter what the cameras say, some drivers are refusing to pay dozens of $40 speeding fines.

Who? Police officers.

In the last eight months of 2007, Montgomery County's new speed cameras recorded 224 cases in which police vehicles were recorded travelling more than 15 kilometres an hour over the speed limit, according to department records.

Supervisors dismissed 76 of those citations after determining the officers were responding to calls or had valid reasons to break the speed limit.

But that left 148 who didn't have that excuse, and about two-thirds of those citations haven't been paid, said police Lt. Paul Starks.

The police union says officers shouldn't pay because the citations are issued to the owner of a vehicle, in this case the county, and not to the driver.

Police Chief Thomas Manger doesn't buy that argument.

"We are not above the law," Manger said. "It is imperative that the police department hold itself to the same standards that we're holding the public to."

Manger said officers who continue to ignore citations might be disciplined.
