To protect you and your fellow passengers, the Transportation Security Administration (TSA) is required by law to inspect all checked baggage. As part of this process, some bags are opened and inspected. Your bag was among those selected for inspection.

During the inspection, your bag and its contents may have been searched for items forbidden by law such as fireworks, fuels, gunpowder, etc. At the completion of the inspection, the contents were returned to your bag, which was resealed (重新封口) with a “special” lock.

If the TSA screener was unable to open your bag for inspection because it was locked, the screener may have been forced to break the locks on your bag. TSA sincerely regrets having to do this, and has taken care to reseal your bag upon completion of inspection. However, TSA is not liable for damage to your locks resulting from necessary precaution.
