Frequently Asked Questions
Is Crestwood Police radio encrypted?
Yes. Crestwood Police uses P25 ADP encryption. There is no partial access here: routine dispatch is encrypted alongside everything else, so a scanner picks up nothing from this agency at all.
Can I listen to Crestwood Police on a police scanner?
No. Crestwood Police has fully encrypted their radio communications using P25 ADP. No consumer scanner can decode encrypted transmissions.
Why did Crestwood Police encrypt their radio?
The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.
Can St Louis County reverse the encryption decision?
Yes — nothing about the underlying radio technology forces this. It's a decision St Louis County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.
What can I do about Crestwood Police encryption?
Three things carry weight, in this order: a public-records request for Crestwood Police's encryption policy and radio recordings, a turn at the microphone during St Louis County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
