Frequently Asked Questions
Is Florissant Police radio encrypted?
Yes — Florissant Police's radio system runs on P25 ADP encryption. All traffic, including the day-to-day dispatch that used to be the public's window into police activity, now runs encrypted. Nothing from this department is receivable.
Can I listen to Florissant Police on a police scanner?
No. Florissant Police has fully encrypted their radio communications using P25 ADP. No consumer scanner can decode encrypted transmissions.
Why did Florissant Police encrypt their radio?
Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to St Louis County; what's verifiable is what's lost — journalists can't monitor police department activity in real time, and coordination with agencies that stay unencrypted gets harder.
Can St Louis 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 Florissant Police encryption?
Contact the officials who oversee Florissant Police's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in St Louis County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
