Reporter there have been nearly 60 airport attacks in the past year. Most in europe, africa, and asia. Not one in north america. But some Security Experts do worry about u. S. Airports. Weve built up checkpoints and screening procedures and screening technologies, but the front of the airport is vulnerable. Reporter secured areas of airports are from tsa checkpoints on, called the back of the airport. But should we push security out to the front door . And maybe use a model from world trouble spots, pushing security to the entrance roads. Some suggest at least we should harden the front of the airport, physically and with person in the front of the airport does act as a deterrent. David kerley joins us now. And david, how feasible are these ideas . Reporter well, george, its really a question of balancing the risks against the cost. Airports are run by the local entities. Theyre secured by the local sheriff or police, including the front of the airport.
