In Florida, a news person and amateur radio operator are specifically exempted from requirements that do not permit scanners in vehicles. Given the time the section was written and/updated, the intent of the section appears to be that news papers and amateur radio operators provided a public service and could monitor all police frequencies. At the time, all government radio systems would have been "in the clear". There is no specific exemption for "digital" or "encrypted" communications.
