This seemed obvious to me at the time. It was hard to understand why people in the cultural mainstream let themselves get swept up in it. I felt like I lost my country, back then, as they pretty much all went off into crazyland together.
It was obvious to many. It was even a sort of not-funny joke: "The terrorists have already won."
The OK-ing of torture was a clear step into the totalitarian camp and a clear breach with justice, liberalism, and decency.
In the same way it is obvious that internet age gating, digital ID and abolition of physical cash will lead to much worse. But who's standing in their way?
How old are you? I think a lot of younger folks don't fully adjust for important factors: plane hijackings used to be much more common, 9/11 was committed by the second group of Islamic terrorists who tried to blow up the World Trade Center, and 9/11 was the third major terrorist attack by Al-Qaeda in a 4 year span. It's easy now to say that it was a crazy worst-case scenario, but that was not at all obvious then; for all we knew, securing cockpits might have been impractical, and we'd just have to prepare the Air Force to shoot down a couple hijacked flights every decade.
There were real excesses, and I ultimately agree with you that many of them were predictable in advance, but there was no feasible version of a response that did not go at least a little into crazyland. It was a crazy time.
What do you think distinguishes the post-9/11 craziness from the Cold War/Red Scare craziness?
My reason for asking is because I believe that "that's unconstitutional!" has been a failed protest message for more like 100 years than 25 years (and there's threads of state violence at the local and state levels that go back far longer). And IMO that is even stronger evidence that words on an ~240-year-old-doc—and the way some interpret the second amendment in relation to those words—is a completely powerless measure against state violence. The United States is not exceptional in that regard. We'll only have a better country if we constantly, actively, choose to vote it that way.
