Thank you for that.
I'm going to switch gears and take you to clause 24. I have a question on X-rays. Under what circumstances would an X-ray search be the only alternative to effectively search a traveller? I'm thinking particularly, with respect to the backdrop of my question, of vulnerable segments of our population, including pregnant women and potentially people who are compromised because of existing medical conditions.
How often do we actually do X-rays? Are they required? Are there technologies that are really going to minimize, if not eliminate, cases where we have to resort to X-rays?
