Frequently Asked Questions
Is Trenton Township Police radio encrypted?
Yes — Trenton Township 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 Trenton Township Police on a police scanner?
No. Trenton Township Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Trenton Township Police encrypt their radio?
Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to Mercer 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 Mercer 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 Trenton Township Police encryption?
Contact the officials who oversee Trenton Township 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 Mercer County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
