I too was under the impression that this was an airport/TSA employee that she is alleging tampered with her bag. I know, when I just travelled less than a week ago domestically in the US I was asked as I turned my bag over if it was unlocked. It is required to be. They have TSA approved locks now (which I have and don't use) but they don't seem to be widely accepted by the TSA (ironic, I know!). I too found upon my arrival home the lovely notecard letting me know that they had fully searched my bag and it would have been easy enough for someone to add or remove something from my bag and I wouldn't have had a clue until I arrived at my destination and unpacked it.

My only thought about this idea that an airport employee tampered with her luggage and planted the drugs is they did a really poor job on completing the "connection". They surely would have needed someone on the other end in Bali to "lose" her luggage for her or re-handle it to remove the drugs to further distribute or keep them. It seems a bit idiotic to me that an employee would have planted them in an effort to smuggle without having an aware party involved elsewhere on the trip.
