Gaynor McLaughlin: Yes, you are absolutely right: we do. Therefore, any sort of selection or targeting should be based on behaviour and not on appearance. The behaviour is one way of doing it. It certainly should not be done in any way that is discriminatory. I take your point about creating weaknesses. Given that it is a network operation, we need to be absolutely clear how we feed operations that may have been deemed a lower level of risk into the network. We need to be clear whether it can feed seamlessly or whether there needs to be another layer of security before they go on to the network at another airport. That then becomes an operational decision, rather than a security decision.
