Hello folks, I am planning to write a nonfiction book about a company. It will be anecdotal, based on many negative personal accounts which all are found across the internet, with some liberties for storytelling purposes. It's basically just a compilation of negative experiences. A book that that comes to mind is Fast Food Nation, which reveals all sorts of horrible things food industry does, with a lot of personal accounts. It gets away with doing what I described above. Now, my question is, what are the precautions this author took so he didn't get sued for smearing on these big companies? what laws protect him? Another question I have is, since I am going to quote and "rewrite with storytelling in mind" a lot of the negative accounts I'll find online, do I need permission from those people before I base my rewritten anecdotal stories on their experiences? Thanks!
