We practise both safety and security at airports. I gave the example of an incident in the taxi area of the runway where perhaps the lighting or the markings need to be changed a bit, and both the pilot and the people on the ground, the airport authority personnel, see that some changes are necessary. That takes some time, so when the airplane touches down at the airport, the airport authority assumes responsibility for the safety of that aircraft and the people inside it, to make sure they bridge properly and people get off the airplane in a safe way.
Security is certainly another part of all that, but the Aeronautics Act and what we're talking about primarily is safety.
