"More than just Lincoln's tragedy...."

[RJNorton]

"What if I had turned my head around and saw Booth before he pulled the trigger?"

Hi Craig. It has been suggested that Rathbone actually did see Booth out of the corner of his eye. Rather than react immediately Rathbone froze. This failure then led to his lifelong guilt feelings and later family tragedy. IMO, there is no way to prove this speculation.
