For those that already "get" what's going on with this, I would recommend that you look a layer deeper.

That is, for those "good" and "virtuous" people that are in thrall to the Establishment and take their marching orders from their televisions, neither this nor anything even more blatant will be enough evidence to convince them they were on the wrong side.

The conclusion is that they are not evaluating the evidence at all. That's not how they make decisions, if they can be said to make decisions at all. Wise people should stop thinking that it's somehow a matter of enough evidence about what's going on piling up before everyone else "gets" it.
