Bit off track but....
In the Philippines, Manila International Airport, every bag, suitcase and item whether it be a pram or box is x-rayed before you even get through the front door and enter the checkin areas. To get to the departure gates you go through an extra two check points with another x-ray of hand baggage and everyone (not just those that make the walkthrough beep) is frisked and scanned.
For a nation that in many ways is so far behind it makes sense really. They are doing it so why aren't we!!
