CBS July 4 Coverage Used Altered Footage

Those who watched Boston’s revered Fourth of July celebration Monday night on CBS were treated to spectacular views of fireworks exploding behind the State House, Quincy Market, and home plate at Fenway Park, among other places — great views, until you consider that they were physically impossible. David Mugar, the Boston-area businessman and philanthropist who has executive produced the show for nine years, confirmed yesterday that the footage was altered. He said this was the first year such alterations were made.
