The NSA and Homeland security aren't particularly interested in stopping terrorism. I'd say that they're far more interested in tracking dissent
The occasional successful attack justifies their existence.
Less than a year after 9/11, and during a CODE RED alert weekend, I had a kid on my game server who had talked to me about being a fundamental muslim and having issues within that realm make a comment
"That's OK I"ll be dead tomorrow anyways".
Now, if ever there was a case that just stood out like a sore thumb and asked to be investigated, I couldn't think of something better. I was also, at that point just worried about his mental health, generally.
Turns out that the much-touted 1-800 terrorism hotline was already shut down.
It took me almost an entire day to find someone who would take my 'tip' and do something with it.... and that was pretty much in the middle of the post 9/11 hysteria. That's right... we're supposed to turn in tips about possible terrorism but almost all of the avenues of reporting have been shut down.
Not that I took the terrorism hype very seriously to begin with, but you'd think that they'd at least keep up the first layer after the facade.
