Hate having the TSA open up and steal items from your checked baggage in the US on domestic flights only? Throw a lower receiver into each bag. It's technically a firearm and so subject to the strict integrity rules requiring sealing at the ticket counter. You don't have to be a 2a die-hard or even have a single functional weapon to exploit this loophole. Or you could get a backpack that expands to the same size as the largest domestic carry-on and skip checked luggage altogether. Items you can't take in carry-on bags but are allowed in checked bags: alcohol, actual or improvised weapons.
