The TSA is the result of a brief moment of unity where we decided we feared someone else more than each other. Eliminating it might save money and simplify travel, but it won't touch the fear and ignorance.
Whatever optimism we had died during Vietnam, if not long before that.
The Patriot Act was a renamed law (several laws actually) that the the FBI/CIA/NSA had been trying to get passed for decades, it was a wish list for them that was rubber stamped shredding what little protections left in the constitution
In the decades before 9/11 the US government had the decency to lie to the American public about it. They told us that America was so great because it would never do those kinds of things. Those types of activities were held up as examples of horrible atrocities communist nations subjected their citizens to.
Even as evidence came up from time to time showing that the US government didn't always live up to those ideals they continued to be expressed as what this country stood for. Post 9/11 that was no longer the case. This might be a more honest American government, but I can't help feeling like we've lost something.
