Forum Post: Mobile police updates/police scanners on your phone?

I know for a fact, that most police stations have an internet accessible police scanner. Any area that is being "Occupied" by protesters, should have a few people listening in on police actions, commands, and movement in general. Being more organized in this sense would be a good idea. I'm sure that with smartphones and such, there's a way to find a local scanner for nearly every occupied area. Somebody better equipped than me could make an app for iPhones, even. I'm a little homeless at the moment, stealing my internet and power from a McDonalds tonight. But thinking tactically like that is a good way to ensure that nobody runs out of battery power before anything significant happens on the front lines. Any thoughts or comments on why this hasn't been done yet?
