This is the device adopted recently by TV reporters that they think portrays them as objective. As in, "Socrates, an allegedly Greek philosopher..."
Maybe he always wanted to be a reported when he grows up?
Hitler, allegedly a bad man
Albert Einstein, allegedly a scientist
Bill Gates, allegedly not starving this year
Mother Teresa, allegedly helpful at times
Joeseph Stalin, allegedly paranoid at times
I think the list can be longer, but what is the point? But hey, add that magic "allegedly" in the sentence, and noone can take issue with you for choosing sides, or standing for anything!!! YUCK!
