From what we are seeing these days from the FIB, I now have my doubts about the assassination as well.
Their prime suspects were jealous husbands or boyfriend of the many women that King banged. In the early 1980s, I was assigned to a dinner table at an event with Rev. Ralph Abernathy, his closest lieutenant, who who explained to us that women were Martin's weakness and it was a constant battle to screen out those who might be dangerous from entering his hotel suite.
Like the King family, he did not believe James Earl Ray was the actual assassin.
Since we know the FBI has always been corrupt, I’d like to see a new investigation into this.
