Alaska Airlines flight attendant: if I don't get the missing video screen back, no one gets off this plane

Jeff sez, "Flying in from Miami to Seattle this morning on Alaska Airlines Flight #17, I was somewhat amused (and a bit horrified) when the flight attendant said that the cabin doors would not be opened and that passengers would not be allowed off to catch connecting flights if the last video player (digiplayer, as she called it) was not returned. Partly, I'm amused because of the ridiculousness of the threat vs. the magnitude of the crime but also I have to wonder if this is against FAA regulations. I also have a brilliant tip for Alaska - when you rent a digiplayer, note down the seat number.
