Frivolous post here: Years ago, in a story about punk rock, the Times insisted on referring to “Mr. Rotten” and “Mr. Vicious.”
The Times mandates courtesy titles (Mr., Ms., etc.) only in news stories, though it drops them for some dead people and those it arbitrarily considers evil enough not to deserve them. For example, Osama Bin Laden lost his Mr. after US forces killed him in May. But Saddam Hussein was recently still being called Mr. Hussein, as Slate notes.
