And it's easily decoded when you have the keys which, based on every other department that uses them, won't take long to leak or be cracked.Lot of folks use SDR setups on a PC to decrypt and stream police and fire radio to a service like Broadcastify
I assume it depends on where you live, but police scanner radios have been around and on the shelf at stores for half a century. I imagine it's a legal grey area similar to radar detectors.
