Watching a guy get hung isn't much of a blaze of glory, its not a firework show like a firing squad, or even climatic like a beheading, but rather unimpressive quiet and usually the guy swinging will soil him self.  Rather undignified.

 To address your first point, the data may have been a result of correlation and causation.  I haven't seen any research on it, nor do I really feel like doing it.
As for your second point, typically a public hanging is a solemn event.  But, I doubt a hanging in Time Square with Pay-Per-View could provide such an environment.
