mlk suicide letter

i was browsing the web and i came across a website dedicated to dr.martin luther king jr. sorry i cant remember the name of it, my computer started overheat like it always does and bugged out therefor closing out on its own. anyway i was able to save this document before it closed out. apparently the fbi wrote a letter to dr. king urging him to "off himself" before they will have to take matters into their own hands.. well here it is. tell me what you think. think its authentic?:

ok so i realize its a little small for those of you who cant see it says the following:

king, look into your heart. you know you are a complete fraud and a great liability to all of us Negroes. white people in this country have enough frauds of their own but i am sure they dont have one at this time that is any where near your equal. you are no clergyman and you know it. i repeat you are a colossal fraud and an evil, vicious one at that.

king, like all frauds your end is approaching. you could have been our greatest leader. but you are done. your "honorary" degrees, your nobel prize (what a grim terce) and other awards will not save you. king i repeat you are done.

the american public, the church organizations that have been helping- Protestant, catholic, and jews will know you for what you are- an evil, abnormal boast. so will others who have backed you. you are done.

king, there is only one thing left for you to do. you know what it is. you have just 34 days in which to do (this exact number has been aclocted for a specific reason, it holds a definite practical significant. you are done. there is but one way out for you.
