We don't ask for the approval from the government to print things. But by the same token, we do want to know if there's something that would hurt someone [if we disclose certain information] -- and what it is. Then we make very careful decisions and talk about it with dozens of people [including their editors and top government officials] before the actual story runs. It could conceivably be too sensitive: say, if you find out -- through one means or another -- that somebody had a spy by a certain name in a foreign government and that person would be immediately killed if it were revealed.
