This site is claiming to have received an exclusive statement from Roberts County Sheriff Dana Miller (see link in story) that it did happen, but I'm not finding independent verification from an actual local media entity either. That having been said, I'm not arguing that the source of this story isn't reputable, just seems to be an independent journalistic story, so judge for yourself: Police searching for “storm chaser” who pulled gun on farmers
You would think it makes the evening news. I do think it's real. FWIW, The story (also linked in the Bear Cage) lists some details in the statement that would be easy to verify(for those who want to), including witness names, locale, an actual license plate number and make/model(the story says a white Chevy Blazer; not a Chevy Cruze). A basic license plate search matches (albeit non-official). If it is false can you imagine the potential legal headache for falsifying a report from law-enforcement and falsely indicating the involvement of a private citizen?
