Have not had the chance to see the show yet...
I have to agree with Kraigway. As a police officer the most influential gunfight (one way as it was) was "The Onionfield". I'd read the book, and seen the movie. At the time I was a pretty active cop. Every current Officer should see this movie if not read the book.
While the FBI shootout and L/A bank robbery are landmarks... these situation's have presented before. The FBI shootout at little bohemia, and the triangle sports shootout in NY are just two examples.
Based on the conversation in this thread... It seems the show is a politically correct popular history view of well studied shootings. IMO comparing war to a shootout is like saying a bathtub is just a very small ocean.
