That's a very good argument, and I thank you for raising it. We're lack data. We've vastly improved our management system by going after data through our oversight officers. In fact, we lack public feedback. We're trying to develop a system in which travellers, when leaving the screening post, would have a 1-800 number or an instant messaging contact to give us their feedback.
The 24, 21 and 14 complaints received in recent years have been subject to the same investigation method, whether they concerned official languages or a security violation. I myself receive each of the complaints and each of the letters before responding to the people concerned. We take this matter very seriously because, for us, a complaint is used to improve our service.
