The use of smart phones and social media has changed the way we can monitor an incident. If you live or work in a major metropolitan city, there is a good chance that there is a live feed available of your police department and emergency services. Broadcastify and RadioReference are both good sources for live feeds.
If your company has a Special Operations Command (SOC) or Emergency Operation Center (EOC) you should get the links to the feeds prior to an incident. There are several iPhone and Android apps that have live feeds from Broadcastify preloaded.
