Actually, the issue concerning locked bags had to deal with passenger complaints to the airlines about bags that had non-TSA
sanctioned locks that were cut to allow the agents to inspect the bag or bags that did not make a flight due to non-TSA
sanctioned locks that couldn't be opened and inspected in time to make the cutoff for the flight. There are baggage locks out there that are designed to comply with TSA
regulations, mainly that the TSA
has master keys that can open the lock quickly and without damaging it. Any good luggage shop should have them. As mentioned previously, locks and security are there to keep the honest folks honest.
