This application allows you to listen, live, conversations of the police in some countries (USA, Canada, Germany, Italy, etc. ). But nothing in France. Choose what you want to listen by selecting the "Top 50" or desired area, or even what he could say close to you (within 250 miles). I could not believe that these conversations could be live, but it turns out that yes even though it is often difficult to understand everything (they speak too fast for me). You can see how many people listen to a particular radio. Just click on one of your choice and listen . . . and possibly wait for the arrest of David Hasselfoff for driving while intoxicated. The options allow, among other things, to have the information on the frequency you are listening, alert codes (eg 10-10 for a fire fight in progress). I also reassures readers about David Hasselhoff (not Hasseloff as I write) that we should not wait because it is unlikely that we talk to him, at least in the scanner radio online in Los Angeles . .
