I do not believe that a man should take the law into his own hands... But on the other hand, I am the law! As a young man in the Belgian police force I shot down a desperate criminal who sat on a roof and fired at people below. In a state of emergency martial law is proclaimed.

“Let them do what I have done.”
Often attributed, but without a contemporary source, as a remark on being asked to contribute to charity for the poor. See for example Commodore (2009) by Edward J. Renehan
