Did Rathbone get blamed?

[Anita]

I don't remember reading that he was blamed for Lincoln's death. Rathbone's son wrote that he wasn't in uniform and was unarmed.
He got to Booth as quickly as he could.

Rathbone blamed himself not only for not stopping Booth before he fired the gun but also for letting Booth escape. He may have imagined that others thought as he did.
