Did James O'Keefe say something in the video or somehow nullify what the others said?

I honestly don't know. I haven't watched it.

But, video evidence is video evidence. Interesting that you would disregard video evidence from a cameraman you don't like, and yet maintain that a video you've never seen nonetheless exists. I suspect you have a better grasp on reality than you show here in the Open, but I suppose I cannot be sure of that.
