I don't know where the evidence is that the thief is more likely to be working for the TSA than baggage handling. Both have been proven to be theives. Phx's suggestion that it is "more likely" to be the TSA is nothing more than conjecture.

You had a lucky escape not getting the $100 voucher. You are entitled to cash.. and had you accepted it, that would have been a done deal. If you have the damaged shoes and the damaged bag, I cannot see what their defence is. The only possible one is that your bag was not adequate for travel, but they would have to be able to prove this and perhaps why they accepted in the first place.

Hold out for cash.. you are entitled to it. You should also complain to the DOT about their failure to address your complaint.
