Evidently, the newsworthy part of the video is that the protest was in support of some radical professor that is tied to the Rev. Jeremiah Wright.
I imagine that Breitbart intended to build the connections and tie it all to Obama before releasing the video, so that it would have some context.
Context is everything.
Perhaps someone else will tie it together.
I sure miss Breitbart. Every time I think of him, I am saddened.
