I first saw this on Robert Scoble's blog late last night and then I just read Nathan Weinberg's blog and saw it there, after seeing it twice I investigated a little further. It seems a racist website has a top billing on Google (complete with sitelinks!) for keywords related to Martin Luther King, Jr. Chalk full of inaccuracies and hate, its really not a "true authority" on Martin Luther Kin Jr.
This is actually one of those times when looking at the SERPs once and a while and really gaging if your top authority is correct and fixing the errors that occur would be a GOOD thing. Matt Cutts - if your listening go read Tuttle SVC to get the full information.
Here's my contribution!
