When we began unpacking our bags we found that two of them had been opened, with a Notice of Baggage Inpection tucked inside. The notice reads as follows (boldface added by me for ironic effect):
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 physically inspected. Your bag was among those selected for physical inspection.
During the inspection, your bag and its contents may have been searched for prohibited items. At the completion of the inspection, the contents were returned to your bag.
If the TSA security officer was unable to open your bag for inspection because it was locked, the officer may have been forced to break the locks of your bag. TSA sincerely regrets having to do this, however TSA is not liable for damage to your locks resulting from this necessary security precaution.

We appreciate your understanding and cooperation. If you have questions, comments, or concerns, please feel free to contact the TSA Contact Center:

Inasmuch as we did not lock our bags, we did not force the TSA agents into having to do anything they might regret in fulfilling their legal requirements.
The TSA is a division of the Homeland Security Administration, whose long arm has reached out to us at two other points (that we know of) on our return to the States. In applying for private health insurance we signed an agreement acknowledging that the insurer would provide information about our health records to HSA. Likewise when we opened a bank account we agreed that the bank would provide our financial information to HSA.
