I've had this hit me directly with a serious sting. A company in which I was employed became subject of a state investigation, and the local newspaper wrote a story about the problem including a quote from a state investigator something like this: "They definitely have a problem (with XYZ)." XYZ was done in my department. The state investigator had made no mention of XYZ. The reporter had simply clarified the quote erroneously; XYZ had nothing to do with the problem. The state investigator would not say that he was mis-quoted, because the parenthetical material is not part of the quote, and the paper refused to correct the story for the same reason. But to any reader who does not know this obscure exception to the rule that what's in quotes is what they said, it meant I was the smartest guy in the room when and where things went bad.
