Virginia Scanner Law
This is from the Virginia Code and is the only known scanner law:
§ 18.2-462.1. Use of police radio during commission of crime.
Any person who has in his possession or who uses a device capable of receiving a police radio signal, message, or transmission, while in the commission of a felony, is guilty of a Class 1 misdemeanor. A prosecution for or conviction of the crime of use or possession of a police radio is not a bar to conviction for any other crime committed while possessing or using the police radio.
