Insurance

I hear the much awaited "book" is soon to be sent to the publisher.  I'm wondering if the author has the forethought to purchase the insurance policy that will protect them when/if they are sued over the content?  Guess we will know soon enough.  Seems like a small investment when writing something such as this.  I know of a few attorneys that are anxiously awaiting the release of the book.  This could get interesting.   Time will tell.
