I doubt they'd believe it. The TSA I've dealt with over the past few months are pleasant, courteous, efficient (compared to their predecessors), and utterly rigid. There's a mental checklist, and their local supervisor to please, and they follow that to the letter.
They've been pleasant about film (asking whether it was 800 speed or faster), but I've checked my tripod and an informal chat with one this last trip (while they examined and reexamined my laptop bag), suggests that tripods would be dealt with somewhat more carefully if carried on. The size and hollow nature were mentioned as concerns.
