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!
See the related link below. There are several others available sources, which you can find with any search engine.
There are people that like to share and have their scanners either part time or try to have their units hooked up all the time. There are websites that carry these broadcasts from these kind sharing individuals for various geographic locations around the USA and even in some cases from different countries.
Listed below is one such website in the Related Links section. This particular web page appears to have the need to have you listen through the Real Player. Many web pages that offer this ability to listen to live scanner traffic usually work through various media players including what is usually supplied with MS Windows software on PCs.
Links will be added as they are found.
