I don't have any strong feelings either way about whether Drudge was good or evil for reporting that Prince Harry was in Afghanistan. Obviously there are times when news outlets should consider not reporting things, but on the other hand one gets a little uncomfortable when there's a conspiracy of silence so large that it suggests that the media is simply an adjunct of the government or state.
Still, as others have suggested, if, say, the New York Times had broken this story it they would have been accused of painting a bulls eye on his head so The Terrorists could kill him faster.
