It's hard to believe it's been a decade since the country watched in horror as terrorists crashed planes into the Twin Towers. In the 102 minutes that passed from the first impact to the last Tower falling, the nation changed. America had been attacked on its own land and it made the country united, resilient and determined. Now, 10 years later, Americans will never forget.

The Department of Homeland Security was created in the wake of 9/11. Intelligence officials are constantly working to keep history from repeating itself and that means more communication and sharing between federal agencies. Of course, terror isn't the only threat. Our panel of experts, Rich Cooper, Col. Douglas MacGregor and Mickey McCarter walk us through what's changed in a decade and where the country is heading in terms of its national security.
