Frequently Asked Questions
Is National Parks Service radio encrypted?
Yes — National Parks Service's radio system runs on P25 AES-256 encryption. This agency encrypts all of its radio communications, including routine dispatch. The public, journalists, and even other first responders can't monitor its activity.
Can I listen to National Parks Service on a police scanner?
No. National Parks Service has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did National Parks Service encrypt their radio?
Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to Parishwide County; what's verifiable is what's lost — journalists can't monitor other agency activity in real time, and coordination with agencies that stay unencrypted gets harder.
Can Parishwide County reverse the encryption decision?
Yes. Whoever made this call for National Parks Service can also unmake it; there's no technical lock-in. The approach that has worked elsewhere combines public-records requests, direct council pressure, and a coordinated local coalition.
What can I do about National Parks Service encryption?
Ask for the paperwork first — the policy that authorised encryption for National Parks Service, and the recordings themselves — because a specific request is harder to wave away than a general complaint. Then take what you learn to a council meeting, and bring others from Parishwide County with you.
