Conspiracy theory

I saw the movie Due Date. I think it was chiefly financed by the TSA.
In the movie, due to a minor incident, a man gets kicked off a flight and put on the no-fly list. You could say it is just a wildly improbably occurrence that is just the set up for a bad comedy.
Or is it?
The TSA only really functions when the American population are living in total fear of terrorist attack. Or fear of the TSA itself. Face it, if you have spent hundreds of dollars on a flight, and probably even more for the vacation, the last thing you want is to be kicked off your airplane. And if you decide to exercise your constitutional rights, what are the odds that that will happen.
If the TSA keeps people scared, they’ll shut up and do whatever they are told to. And then the TSA can say that no one is complaining and keep racking in massive amounts of government money for security theatre.
