not sure if i made my original point correctly. putting away the camera is entirely related to terrorism, which is why its perfectly reasonable to respond with "I am not a terrorist" (taking pictures of the plane for future blowing-up operations)
Next time a cop pulls me over I'll tell him: "I'm not a turtle". Or "I'm not lightbulb". Or this: "I'm not a tea leaf". And hope they are not looking for an escaped turtle, a lost lightbulb or a tea leaf that jumped out of a tea cup.
