Recall the story about the Little Boy Who Cried Terrorism?
And even though they MIGHT be doing this intentionally, I've read over the past few years, starting a little while after THE FLYING IMAMS, that plenty of people think that it is FUNNY to scare Americans in airports, so they intentionally try to do so -- of course, meantime, some of those who have that strange sense of humor have become very rich with discrimination lawsuits which may have encouraged many others.
I've read so many books and articles about terrorism, that I am DE-sensitized to feeling FEAR, of any type, much less outright TERROR.
Terrorists and terror attacks are simply a FACT of life.
