Why Panic Spread So Quickly At One Of America's Busiest Airports

Noisy fans watching live TV coverage of the Olympics as well as a race starter's pistol may have started the panic inside New York's JFK Airport Sunday. The panic spread like a contagion, from terminal to terminal to terminal. When people saw others screaming and running, they joined in the stampede. Security expert Bill Stanton told Inside Edition: "It's the herd mentality. Someone sees someone all panicked and they get panicked and it has that domino effect." #InsideEdition
