Exactly. I don't have any rose-colored glasses, nor do I harken back to any halcyon days where the government was just completely honest, free from corruption, and always did what was in the best interest of the people. The United States government has never done that.
However, I do firmly believe that 9/11 had to happen before they could "come out" with what they had been doing for years. Of course, there were terrorist attacks before 9/11, but those were mostly small time acts perpetrated by Americans. The people in charge know that we won't give up our liberties (again, knowingly) because one of our own did something crazy. We know other Americans, and we know that the majority of them aren't up to any no good.
No, to give up our rights, we needed someone who didn't have any constitutional protections. A foreign enemy, but one that could be living right here amongst us. They could be using our email systems our cellular networks, our internet service providers!!!
You see, the terrorists hated our freedoms. And they were using them against us! So of course, the only obvious solution is to get rid of the freedom. With freedom, comes risk. Once the average citizen had become stupid, fat, and lazy enough to care more for their own comfort and perceived safety than being free, it was time to drop the hammer on us. Now that the precedent has been set, any legal victory or victory over the minds of people that can be attained by the minority who treasure their freedom and can actually see and understand what is happening can be countered simply by giving some relatively small incident wall-to-wall media coverage for a few weeks, then letting the "pundits" sit and tell everyone how anti-American it is to not want to do "x". (x being reading everyone's emails, listening to everyone's phone calls, banning guns, placing a large urban area under martial law, or warrantless this or national security letter that...the list goes on and on.)
So, essentially, any time the people on the side of good win back one step of freedom or due process, we take 5 more steps down the road to slavery. This is why it's so egregious now. Someone essentially disabled the firewall (the public caring and fighting for freedom), then used a root exploit (a perceived massive threat to safety sold to us by the media) on the constitution.
The only way to fix it is to remove the offending exploit (stop caring about every little incident that occurs) and put the firewall back up (make people care about freedom again). Unfortunately, given how we are all asleep at the wheel, there's a snowball's chance in hell of that actually happening. As long as the average citizen has food, booze, sex, and "Ow, My Balls!" on the TV, why would they want anything more?
