Only two kinds of witnesses exist.  The first live in a neighborhood where
a crime has been committed and in no circumstances have ever seen anything
or even heard a shot.  The second category are the neighbors of anyone who
happens to be accused of the crime.  These have always looked out of their
windows when the shot was fired, and have noticed the accused person standing
peacefully on his balcony a few yards away.
