It must be a rhetorical question

From here:

One "top Egyptian editor" told the Wall Street Journal back in 1991 about a conversation he had with Saddam. "I remember his saying, 'Compared to tanks, journalists are cheap--and you get more for your money.'"

Glenn Reynolds pointed to the item that contains the above, and later asks "Is it ethical not to expose these people, if we find out who they are?"
