"I'm sorry, I can't give you those," the man said. "I stole this car."
"You WHAT?" the patrolman asked.
"Yep," the man replied, "and I killed the owner. She's in the trunk. Want me to open it?"
At that point, the patrolman realized this was not a routine speed violation and he needed backup, so he called for reinforcement. In short order, another car pulled up and the second patrolman approached the speeder.
"Sir," he said, "I'm going to need you to get out of the car slowly and open the trunk."
He did. The trunk was empty.
"I don't understand," the second patrolman said. "My partner said you stole this car and had the owner's dead body in the trunk."
Then, the speeder produced his driver's license and registration, handed them to the patrolman, and said, "Yeah, and I bet he told you I was speeding, too."
