When I travel, I usually carry a backpack and inside, a small leather pouch with various creams and perfumes inside along with a laptop in a laptop briefcase-style bag.
The first time I traveled with this leather pouch, the officers didn't ask me to throw away / empty the contents of my pouch. I thought they just didn't care. But since then, I've traveled many times to many different countries and have never been stopped. Sometimes, I would have various liquids inside in containers of up to 100 ml that otherwise have to have been thrown out. The laptop on the other hand, if I forgot to put it on one of those trays for scanning, the officers would catch it inside my backpack and ask me to remove it from its pouch and place it in a tray for scanning.
Is my leather pouch able to block bag scanners so officers aren't able to see its contents?
