Frequently Asked Questions
Is Tustin Police radio encrypted?
Yes — Tustin Police'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 Tustin Police on a police scanner?
No. Tustin Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Tustin Police encrypt their radio?
Ask why, and the answer is usually officer safety, sometimes operational security. What is harder to obtain is any documented case in Orange County where an open channel caused harm. The costs need no such documentation: reporting on police department response slows down, and mutual-aid coordination gets more awkward, immediately.
Can Orange County reverse the encryption decision?
Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.
What can I do about Tustin Police encryption?
Ask for the paperwork first — the policy that authorised encryption for Tustin Police, 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 Orange County with you.
