No offense but I find that a bit of a pedantic interpretation of my post.
Twice-removed observation:
"vindicated of" roughly equates to "absolved of"
"vindicated by" roughly equates to "justified by"
One phrase implies that the suspicion is withdrawn and found to have no standing. The other phrase implies that the action was excusable and is acceptable due to other circumstances or actions.
A person who is accused of murder, and is later found to be not guilty based on evidence that they were not there at the time, might be said to be vindicated of the accusation.
A person who is accused of murder, and is later found to have been acting in self-defense against an attacker, might be said to be vindicated by the attack.
That is my understanding, other interpretations may exist
