Traffic Inspector John

You work night shifts as a taxi driver. Today, you were driving with a client who was wanted. You knew this and tried to avoid being caught on surveillance cameras. But when a traffic police officer's car appeared ahead, your hands began to sweat with fear. You hoped he wouldn't stop you, but in vain. You pulled over to the side of the road and opened the window. The officer timidly approached you, and you read "John" on his uniform.
"Good evening, documents please."
