How can you hear police radio in your neighbourhood?

Well you have to buy a desktop police scanner at radio shack or online, then put the walkie talkie on vox mode next to the speaker of the scanner. If you want to listen to police scanners for free, download free online scanner from this link witch you can copy paste, http://www.wlfd.com/staticpages/index.php/scanner_guide F.Y.I. This program is free therefore you can't control the scanner, but you can find one close to your area. Hope this helps!
