The incident highlights the peculiarities and seeming contradictions of local, state and federal gun laws inside the nation's airports: It is legal for a passenger to travel with a firearm and ammunition in checked baggage, but inside baggage claim or at a ticketing counter, that person might otherwise be breaking the law if the weapon is out in the open or carried on their person.
Five people were shot dead and eight wounded in a baggage claim area at Florida's third-largest airport, and law enforcement sources tell CNN the suspect had legally brought the firearm and ammunition in his checked baggage while flying from Anchorage to Fort Lauderdale.

The Florida Legislature next week was scheduled to debate a bill that would allow firearms to be carried at, among other public places, airports.

The debate over how to secure airports has been happening at airports around the world.
Thirty-two people were killed in March 2016 at Brussels Airport in the Belgian capital after suicide bombers detonated explosives at a ticketing and check-in area, shutting down the airport for 12 days, and at a train station. An attack at Ataturk Airport in Istanbul in June killed 45 and injured hundreds more.
