Being a police officer be dangerous and life threatening. But it can also be tiresome and, let’s admit, boring at times. Sitting in a patrol car for hours looking for speeders and potential troublemakers would make anyone wish they were elsewhere, like bed.

Both officers were in full uniform in their marked car. The witness said "they were sleeping so soundly they didn’t even stir."
