Thank you for doing so.
I don't believe for a second that he didn't expect this event to trigger the reaction it did. I think this whole thing was a lefty setup for sparking a race war, somewhat similar to Charles Manson's "Helter Skelter".
Obama pals Dohrn and Ayers' Weather Underground and Manson basically had the same agenda: to incite a race-based, black vs white, revolutionary overthrow of the capitalist class.
Not saying he's as sick in the head as Manson. Only that the basic overall plan appears similar.
