All right. I'll answer in English, since it's a complex matter.
That's not to say that the other question wasn't complex also.
The best practice for international security, as demonstrated by Mr. Sela, is precisely risk management, it is to identify those who are high risk and those who are trusted travellers. The way that the random screening system works with CATSA now is that every single passenger is treated the same way.
This is the tension that I was talking about. The best systems, as Mr. Sela rightly identifies, separate out those who are risky and those who are trusted, but our current system treats everyone exactly the same way.
CATSA right now simply cannot, under its legislative mandate, treat individuals differently. It cannot. It cannot do investigation. It cannot look at your identity documents. It cannot participate in that trusted traveller system.
So there is a tension between CATSA's desire to emulate best practices and the regulatory instrument that describes that everyone must be treated exactly the same.
