Query: How Could They?

Even if every word of this book is fact (which I am sure it is not), how could they list their gripes with Elvis one after the other? They apparently never had the guts to stand up to him to his face, so they decided to write a book and tell the whole world all the things we hated about Elvis. Well, I'm sure working with Elvis was hard, but that was what they chose. When I read this book, only few words came to mind, backstabbers, dis-gruntled employees & jealousy.
