X-Ray question
Passing through a european airport last week I was very surprised to see the x-ray machine operators sitting with the screens in full view of people in the departure lounge. I have always thought that what the operator sees is hidden from the public whenever possible for security reasons. In this case it seemed fairly simple for someone to stand around watching other passengers baggage being scanned. Isn't this, at best, poor practice or, at worst, rather dangerous?
