There are scanners that can allow the average person to listen to police calls, but they may be somewhat hard to find. Many years ago, the "police band" was 1650 to 1750 kHz, and large home radio sets were able to tune those frequencies - people sat at home on dull evenings and listened to police calls - I'm old enough to remember that!

To program a Uniden DC355N scanner to hear police activities, first, ensure the scanner is set to the correct frequency range for your local police departments. Use the manual to find the specific frequencies or codes used by your local law enforcement. Enter these frequencies into the scanner by switching to the programming mode, and then input the desired channels. Finally, save your settings and switch to the scanning mode to listen for police communications.
