Sorry, you’re saying that in Oklahoma if someone has been convicted of a felony at some point in their past, it’s illegal for them to own a scanner? I think maybe you’re confusing that concept with being illegal to use a scanner in the commission of a crime (an extra charge to toss on the pile).
Yeah, he's wrong.
It shall be unlawful for any person to operate a mobile radio capable of receiving transmissions made by any law enforcement agency for illegal purposes or while in the commission of a crime and not otherwise and any person violating the provisions hereof shall be guilty of a felony upon conviction thereof shall be punished by imprisonment in the State Penitentiary for not more than three (3) years, or fined by not more than Five Thousand Dollars ($5,000.00), or by both such imprisonment and fine.
