What surprised me most when researching The Final Truth was that most experts today seem fixated on the first shot occurring around Zapruder frame Z160.  Yet nearly every witness (13 of whom I quote in the book, pp. 133‒136), including Secret Service Agents, county and city law enforcement officers and journalists all reported hearing “the first shot just as the President’s car was turning from Houston Street onto Elm Street, or in the process of completing its turn.”  That’s about six seconds earlier than Z160.  Once we accept this testimony instead of ignoring it, evidence begins to make sense and answers fall into place.  And once we know why the first shot was fired, we can learn when and where it was fired.  That part is not surprising at all.
