Moral Dilemma Day #3 ~ Would you report the robber in question?

You have witnessed a man rob a bank, but then, he did something completely unusual and unexpected with the money. '

He donated it to an orphanage that was poor, run-down and lacking in proper food, care, water and amenities. The sum of money would be a great benefit to the orphanage, and the children’s lives would turn from poor to prosperous.

Would you:

-a: Call the police and report the robber, even though they would likely take the money away from the orphanage, or

-b: Do nothing and leave the robber and the orphans alone?
