Flint, Michigan 2nd most dangerous city in America. Did you know that you that you can listen to their police radio's live on line, I do.
Go through and pause the ones you don't want to listen to.
This covers Australia and there are lots more if google (live scanner feeds)
I listen to them of a Friday and Saturday night when sitting at my computer and when there are emergencies like the vic bush fires. One day while at work I had my scanner on and herd that the Black Saturday fires were threatening an area where a friends property is so I called his work and he went home to defend it. They do come in handy.
I hope this is not a rule breach, if it is please remove.
