That's a confusion born of not spending enough time hanging out with sneaky folks doing shady shit. I remember that in the 90s, the local PD had learned that some folks would listen to scanner traffic to figure out when their rowdy parties were going to be broken up, so everyone could hide and make the scene look calm by the time officers arrived. So they stopped using voice radios for this sort of call, and instead switched to their Mobile Data Terminals. Which was even better, because MDTMON had an alert feature where it'd sound the PC speaker when your keywords (say, your street name) showed up in the decoded traffic. That freed up one partygoer from scanner duty! POCSAG/FLEX were even more of a treasure trove, but that's a story for another day.
