Feel like I got hit with a firehose, but there's definitely a clear picture of complicity and widespread coverup. Maybe not every organization or person were in on it, but they may have let themselves be coerced into looking the other way or remaining silent.
I suppose on the positive side, there are many who tried to expose it and keep pressing - a lot of whom were murdered on 9/11, but also a lot who keep on, despite the powers against them.
