Caught in the Lot

 She called the police because she heard a loud car radio. Two guys non residents, were parked in her driveway. She went out, with the dog. She noticed that they had no front license plate. She walked past the car onto the sidewalk to get the rear plate. The guys drove in to the rear of the communal  parking lot and the driver got out and put something in paper bag into the trunk. She phoned the car's license plate into dispatch. Two officers showed up and spent a lot of time with the guys and then the guys finally left.
