Definitely. It's not just international airports. Every airport, according to the existing legal system, has to have a definition of the perimeter, of what is regarded as the perimeter, the clean area within the perimeter, who has the access, and at what levels. There is a full set of rules and protocols on how it has to be done. The monitoring of this is very important, as are the training of the employees and the drilling of the employees.
One of the biggest problems we are confronted with on a daily basis is that we have 13,000 screeners, and each of those screeners is sitting in front of a monitor and seeing pictures that are changing every seven seconds. How do you ensure, at 4 o'clock in the morning, or at midday, or at 4 o'clock in the afternoon, that the employees are responding at the same level of expectation in a continuous way? The same thing applies to perimeter security.
We are actually at the beginning of the intense part of it because there are a lot of goods entering the airport through the gates. Just think of the deliveries to an airport. Also, every airport is a construction site. There is no airport in the world that is not building a new terminal or a new runway. We're talking about huge construction sites worldwide. Every truck could be loaded not only with metal, but with dangerous items. It is a very valid point and issue.
