A few weeks ago I flew direct (from UK) to ATL for the first time since Sep 11 and I have a question about the new improved security measures.
Imagine I wanted to bring a dangerous/restricted item with me into the US - let's say a modest size pocket knife intended as a gift for an American friend.
The knife would go into my check-in bag (of course) and I would board the plane in London carrying nothing on my person that would be deemed dangerous.
I would disembark at Concourse E in Atlanta and proceed through the immigration booths to the baggage reclaim.
I would then collect my check-in bag (containing the little pocket knife) and would then proceed through the airport to the Terminal buildings and the taxi ranks/buses etc.
However, in order to leave Concourse E and make my way through the airport, I need to go through a security check point where I and my bags are screened and x-rayed.
What happens when the kinife in my luggage is detected? It is clearly an item that is not allowed within the airport's security cordon.
