Solution: take a gun. Seriously.<p>In stark contrast with the requirement that TSA be able to open your luggage (unlocked or backdoored), if you declare a firearm in your checked luggage the TSA <i>cannot</i> - by law - have the means to open your [hard-shell] luggage, YOU must retain the key or combination and must be present to open it when inspected.<p>(Of course, traveling legally with a gun has its own litany of issues, but for those of us who are OK with the basic concept may find doing so helpful against TSA&#x27;s security theater.)
