After last November's deadly shooting at LAX, officials have been looking into what they could have been done better. And in a report released yesterday, one of the simple answers was communication.

For example, during the emergency first-responders had trouble coordinating with each other because their radios weren't compatible. Some of the airport's red emergency phones weren't working properly and passengers were wandering the terminal without information on where to go.

For a look at how address these issues, we're joined by Brian Jackson, director of the Safety and Justice Program for the Rand Corporation.
