Why did Norfolk County EMS encrypt their radio?

Police departments typically cite officer safety and operational security as reasons for encryption. However, encryption also eliminates public oversight, prevents journalists from monitoring police activity, and can harm emergency coordination with other agencies.

Can Norfolk County reverse the encryption decision?

Yes. Encryption is a policy choice, not a technical requirement. Multiple communities have successfully reversed encryption decisions through public pressure, city council advocacy, and coalition building. See our guide on fighting encryption for specific strategies.
