I was returning from Beijing through Narita to Atlanta and was "felt up" and had my luggage checked:

1) Upon entry to the secure area in Beijing
2) Upon entry to the jetway in Beijing
3) After exiting the flight to Narita (before getting to the gate area)
4) Upon entry to the jetway in Narita
5) Upon exit of immigration/customs in Atlanta before my flight back home.

Exactly what weapon or other dangerous material was I suppose to have picked up between the jetway in Beijing and exiting the plane in Narita?
