Skipping the Public Enemies Era
The Kansas City Massacre, the hunt for Dillinger, Machine Gun Kelly's kidnapping scheme, all very important in the history of the FBI. The formative years and events that shaped it to what it is today... and they all go pretty much ignored by this film.
Was this because Public Enemies covered these events (and was a much better film)?
The Kansas City Massacre gets all of about five seconds of screen time. Melvin Purvis gets mentioned twice.
