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.
