You aren't going to win many friends around here by creating a thread with such an explosive title when the actual reported events are just things many of us have experienced as routine occurances.
Bags go missing all the time, TSA interfere with baggage all the time. Any systematic malfeasance in baggage handling is routinely caught by authorities.
If you had titled your thread "bag didn't arrive, what should I do?" you would have got a lot more sympathy.
