cdiver2 I understand that it's just employees that can tamper with bags. That is part of my point. Who is responsible for the employees? I've never lost money in a bank, although I heard of bank employees embezzling money, but if I did the bank would be responsible. I'm betting if you the airlines or the airports were paying out full value of lost goods, or there is a major incident, that security would be a whole lot better, in a hurry. Even if that meant random searches of employees, which does not have to be done along side passengers.
We, Joe public, already have put up with much inconvenience and expense. And it just continues, an example are the new puffer machines. What does each one of those cost and how long will before other more advanced security machines come along? All these new and constantly updated security measures make sure passengers and their bags are checked but you're right, what about the employees? As you say, there are lots of ways to get things in and out. If employees can tamper or steal, as you say, with the bags in these secure areas, they have the opportunity to place something in a bag as easily as taking something from it. If you can get my camera housing from a secure area into a mail truck, it's not searching the mail truck that is the problem. The problem is the secure area is not.
This issue goes beyond stolen items, it has more to do with security. Does it take a maor incident for something to be done? Spending millions making sure passengers and their bags are thoroughly checked but leaving a gaping hole in checking the employees, as you say, is truly a waste of money. And that is something we shouldn't stand for.
