"We put people of concern on the watch list or the no-fly list, so we have a number of layers of security beyond the airport checkpoint. We gather as much information about a passenger as the law allows without profiling"

John Pistole is referring to the security measures that are taken to guarantee the safety of guests in airports. He is stating that the security steps go beyond the airport checkpoint, such as putting people of issue on the watch list or the no-fly list. This implies that people who are considered to be a possible danger are not enabled to board a plane. Pistole is likewise saying that they collect as much information about a traveler as the law permits without profiling. This means that they are not enabled to discriminate against travelers based on their race, religion, or other aspects. The security measures are in location to make sure the security of all guests and to prevent any possible threats from boarding an aircraft.
