To me it all seems quite extreme too, and I agree, who keeps baggage tags? I would definitely consult a lawyer, but I would also be very upfront about everything. She has nothing to hide and once they start this "investigation" they will find that out and realize what idiots they've been. My question is, why are they wasting "our" hard earned tax money on somebody like your mother when there are real terrorists out there?

Good luck to her.
