In the movie "Wag the Dog", Dustin Hoffman plays a Hollywood producer who is hired by the President to create a fake war to take attention away from another scandal. Spoiler alert Near the end, Hoffman's character is upset that the President's re-election is credited to something else instead of his handiwork. Even when told he's risking his life if he says anything, he yells "I want the credit!". I think a similar psychology may be at work in this and other crimes that become (in)famous.
