Albus Dumbledore came to personally believe Sirius Black was innocent during the dramatic events of Harry Potter and the Prisoner of Azkaban. This realization occurred specifically after the confrontation in the Shrieking Shack, where the truth about Peter Pettigrew's betrayal and Sirius's wrongful imprisonment was revealed.
However, it's crucial to understand that Dumbledore never officially proved or cleared Sirius's name to the wizarding world. For the Ministry of Magic and the general public, Sirius remained a wanted fugitive.
The Revelation in the Shrieking Shack
In Harry Potter and the Prisoner of Azkaban, Dumbledore arrived at the Shrieking Shack and heard the full, complex story of the night James and Lily Potter were murdered. Present were:
- Harry Potter: The central figure whose parents were betrayed.
- Ron Weasley & Hermione Granger: Harry's loyal friends.
- Remus Lupin: A close friend of James, Sirius, and Peter, who explained the backstory of the Marauders and their Animagus forms.
- Sirius Black: The wrongly accused, who vehemently denied his guilt and explained the switch with Peter Pettigrew.
- Severus Snape: Whose presence initially complicated matters but ultimately led to him hearing the full confession.
During this intense revelation, it was explained that Peter Pettigrew, not Sirius, was the Secret Keeper who betrayed the Potters to Voldemort. Sirius had, in a last-minute change, suggested Peter as the Secret Keeper believing it would throw off suspicion from himself, a plan that tragically backfired when Peter turned traitor.
Dumbledore's Actions Following the Truth
Upon hearing the evidence and the confessions, Dumbledore's actions clearly demonstrated his personal conviction of Sirius's innocence. Instead of handing Sirius over to the Dementors, Dumbledore facilitated his escape. He advised Harry and Hermione to use Hermione's Time-Turner to save both Sirius and the hippogriff Buckbeak, ensuring Sirius could flee without further capture.
Why Sirius's Name Was Never Cleared
Despite Dumbledore's personal belief and assistance, Sirius Black remained a public enemy. This was because, on paper, Sirius Black was indeed designated as the Secret Keeper for the Fidelius Charm protecting the Potters. From the Ministry's perspective, this fact made him the prime suspect in their betrayal.
- Lack of Tangible Proof: While Harry, Hermione, Ron, Lupin, and Dumbledore knew the truth, presenting Peter Pettigrew alive (as a rat, Scabbers) as proof of Sirius's innocence was fleeting. Peter escaped before he could be brought to justice, leaving no irrefutable evidence for the Ministry to accept.
- Perception vs. Reality: The wizarding world's perception was firmly set: Sirius Black was a mass murderer and Voldemort's right-hand man. Overturning such a widely held belief without concrete, undeniable proof was practically impossible, even for Dumbledore.
Thus, while Dumbledore personally realized and believed in Sirius's innocence during Prisoner of Azkaban, he was unable to officially clear his name, leaving Sirius to live as a fugitive for the remainder of his life.
