Frequently Asked Questions
Is Bannockburn Police radio encrypted?
Yes — Bannockburn 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 Bannockburn Police on a police scanner?
No. Bannockburn Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Bannockburn Police encrypt their radio?
Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is Lake County-specific evidence that open communications ever caused a problem, while the loss of public oversight and the friction with still-unencrypted neighboring agencies are both immediate and real.
Can Lake 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 Bannockburn Police encryption?
Ask for the paperwork first — the policy that authorised encryption for Bannockburn 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 Lake County with you.
