In retrospect, after having long researched these assassination cases, it became apparent that an undefined, fictional undercurrent-- a mystery of sorts, a mysterious veil-- is connected to these two murder cases that also has not been addressed. This mystery continues to be enveloped in the criminal reasoning of how and why these assassins arrived at a point in their lives where they were driven to kill. Certain aspects of these two assassinations spawned a mystifying search for the real identities of Oswald and Sirhan which, in a comparative way, seemed to mirror the structure of popular " whodunit" novels, where the final chapter is usually devoted to unmasking and identifying the perpetrator. Breakdown is instead a nonfictional portrayal " why-theydunit" true crime investigation. The pervasive theme is more why Oswald and Sirhan, as their last acts as free men, succumbed to criminal thoughts that urged them to commit murder.
