> One version of the article laid out both sides of a given controversy, similar to a traditional news story — arguing the case in favor of gun rights, for example, followed by the case for gun control. I'm not sure how this relates to investigative journalism. While investigative pieces give the target of the investigation a chance to respond as part of the article, they do not devote paragraphs to "both sides" of the corruption/wrongdoing revealed.
