      I’m gonna assume you’re not from the US given your lemmy instance. In the US most police radios transmit “in the clear”, i.e., not encrypted. As such, anyone can buy a “police scanner”, or a radio on the same band as police/first-responder frequencies.

      In the internet age, there’s websites (and apparently apps now too), that physically monitor these radio channels and stream them online. Hence, a “police scanner app”. Hope that helps.

      Having typed all that out, the only thing I ask is to let us know where you’re from, please.
