There was a mass panic at JFK airport Sunday night after some people reported hearing gunshots. An eyewitness describes the stampede, lack of communication, lack of coordination between and command over security, cowardice by security officers, lack of guidance during the evacuation, lack of public address during evacuation process, and lack of processing, communication, or guidance for evacuated persons.
Apparently, no one has any idea or has given very much thought for how to evacuate one of the busiest airports in the United States in case of emergency. Also, I don't know if the TSA shoots agents for cowardice or incompetence like the French Army in WWI, but I sure hope there's some procedure.
