I don’t have an IPhone, but several members of our department (fire) do and have downloaded an app that allows them to hear all of the fire calls (both locally and anywhere in the country), including communications when the event is moved to an EMS, Fire or Tactical channel.

Often, news stations don’t have the full story and make assumptions as to what is unfolding, so news of this type may not be all that useful.
