CAAT now permits opening luggage without passenger present

Thaiger reported that the CAAT has recently permitted the opening of luggage of air travel passengers without having to have the owner of the luggage present.

Wonder how they will proceed ? Do they have those TSA lock master keys ? Or will they plainly break open the suitcases ? And how to be 100% sure there will be no theft ?

Why did they not plainly have a system used in many european airports. In case of any suspicious item on screening, they put a clamp like boot/bolt on the suitcase which forces the passenger to show up at customs to have it opened and checked.
