The Hunger Games vs. It Can't Happen Here

While watching the new movie "The Hunger Games" I got to thinking about the statement, "It can't happen here".  In The Hunger Games, the rich live in a lavish city and poor live in 12 different districts and are very poor.  To keep the society in order, the aristocrats hold a game where 2 kids from each division compete to the death and the winner gets riches and fame.  When I think, "can it happen here", my answer at first was no.  But then I started thinking about the question itself.  It's really a poorly worded question.  When you use the word "can't", it's a term with a very difined scope.  It's almost a trick question.  Because if you reworded it to say, "is it likely to happen here?" the answer is clearly no.  If you "can't", the answer changes to maybe.  Of course, "It can't happen here" was written 80 years ago and it never happened.  So maybe it can't happen here.
