I see many people here trying to puzzle out why electronics are under a partial ban from cabins but not from checked baggage. It's a good question, since if there is a fire or explosion hazard on a plane the last place you want it is wrapped in a wad of flammable cloth and synthetics, even if it is oxygen starved.

The only motivation I can imagine is: They want these devices in checked luggage because checked luggage can be inspected without recourse by customs, and without an on-site confrontation. With care, it can be done without even notifying the people who are being checked.

And given the pushback on social media credential disclosure and the reveal that the CIA (and presumably FBI and other agencies) have physical access exploits (probably via USB or DisplayPort) for most of these devices, this seems like a move who's only logical motivation could be easier digital inspection.

Remember, it's the position of the TSA and CBP that non-citizens don't have rights of any kind until they're allowed through customs, and by simply inspecting devices they're interested in quickly and without publicity or confrontation they will certainly be more effective at it.

I'm going to start putting a USB nuke stick in my luggage in an envelope. Just for fun. Maybe I'll label the envelope something nonsensical like "12-16" just to make sure people know it's useless. And in case I (or someone investigating my luggage) needs to plug something into a USB slot.
