Verification Status

We do have per-talkgroup data for Columbia Heights Police Department from the RadioReference API, and used it to set the encryption scope shown above — but no additional human-reviewed source (a live feed check or a dated news account) has been recorded for this record, so treat it as a data-quality correction rather than an independently confirmed verification. Check the live RadioReference database directly for current status.

If you monitor Columbia Heights Police Department directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

Why do agencies like Columbia Heights Police Department encrypt their radio?

The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.

Can Anoka County reverse the encryption decision?

It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by Anoka County officials are policies those officials can revisit when constituents press for it.
