I saw this earlier too. I can now actually buy in to the conclusion Oswald was the only 'shooter'. Still don't buy that he did it without help of any kind, though. Ditto Sirhan Sirhan and James Earl Ray.

Edit: Hadn't researched the MLK assassination for a number of years. Apparently, the King family has said they don't think Ray murdered him. Also, Ray escaped for a couple of days in 1977, along with Ted Bundy. Random.
