"Agreed, one must stay open to the possiblities, but follow the evidence where it goes. My detective friends tell me 90% the evidence leads to a totally mundane conclusion - plot twists and sharp turns of event happen mostly in movies, books, and television."
I wouldn't disagree. My point is that the rule doesn't negate the exception, so the potential for the exception must always be borne in mind. When weird stuff happens, it happens, and it can be very, very weird. The frequency or lack thereof is ultimately immaterial.
