Thanks for the recommendation, I just watched it. Same crimes, by the same type of people, same ways of subverting the truth, with the perpetrators getting away with it, like being stuck in this horrible loop where everything repeats, just the minor details are different each time. I don't know what else to do, but keep spreading the truth. Perhaps each fact of truth going out into people's consciousness will eventually make them stir up a bit and take notice. If it's not 911, it might be the Titanic, or Gaza, or Lady Diana's death (hopefully one day), or a combination of truths coming out.
Coincidentally, about 2 days ago I was thinking of the Titanic, and the thought crossed my mind that her sinking was a deliberate crime. Which I thought was an odd idea, and brushed it off. So I was looking forward to watch this documentary as soon as I saw it this morning.
