Frequently Asked Questions
Is Jacksonville Marine Authority Police radio encrypted?
Yes. Jacksonville Marine Authority Police uses 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 Jacksonville Marine Authority Police on a police scanner?
No. Jacksonville Marine Authority Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Jacksonville Marine Authority Police encrypt their radio?
The reasons offered are almost always the same two: officer safety and operational security. Whether either was tested against a real Duval County incident is rarely part of the public record, whereas the consequences are easy to observe — no real-time accountability, and neighbouring agencies still in the clear left working around the gap.
Can Duval County reverse the encryption decision?
It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by Duval County officials are policies those officials can revisit when constituents press for it.
What can I do about Jacksonville Marine Authority Police encryption?
File a FOIA request for Jacksonville Marine Authority Police's radio recordings and encryption-decision paperwork, then show up to speak at a council or commission meeting. Find other residents or journalists in Duval County who want the same access — state legislation requiring public radio access is the longer-term fix, but organized local pressure is what usually moves the needle first.
