How do i listen in on police radios?
Get a scanner, you can tune into their frequencies and listen to the local police, fire dept, ambulance, county trucks, and many other government departments. Although I believe it is illegal to carry a scanner in your vehicle. I do know if you join a volunteer fire department you get a radio and in most cases you will have the local counties sheriff departments on different channels, and you can listen in legally, as long as you are not using it to help aid in an illegal activity.
