The TSA chooses to stick to the process because that way it can hire anyone who passes a background check and who can read English while providing minimal training. The ability to think and use judgement are not job requirements. Take a look at the people who work for the TSA. They are one step - barely at that - above a mall cop.
Most things will not get the attention of the public because most things have marginal impact on their daily lives. The American people have been told that they have been spied upon for years, yet there are no major demonstrations, no public-wide calls for immediate changes to how government works. Nothing. Nada.
Congress? It's easier to the get the attention of a cat than Congress.
"Passengers should present the following documents to a Transportation Security Officer at the checkpoint:
So they are dealing with boarding because only people with a boarding pass are supposed be allowed through security and only those people who make it through security are supposed to be allowed in the secure area.
"TSA are looking for possible threats, a 9 year old boy probably fell below the threshold."
Then explain the various kids and their families that are pulled out for additional inspection because the name of their 9-year old child matches the name of a middle-aged man on the no-fly list?
"Risner went so far as to point out that those stranded by sudden inclusion on the no fly list had made it back to the US via alternate forms of travel, thus "proving" a lack of air travel isn't preventing traveling."
This guy is saying that despite matching a name on the no-fly list, people are still making it back to the US. Wouldn't that include potential terrorists? How is this list keeping America safe again?
I'm amused by the people saying that Snowden is a traitor and should be executed. I'm fairly certain that is exactly the same thing the British thought about the 'Founding Fathers'. It was okay for those guys to fight against British tyranny but not okay for Snowden to show the true nature of your government.
"The US government seems to think that the Constitution and Bill of rights only apples to US citizens while they are on US soil."
Actually, the US government doesn't seem to care much about the Constitution. Period. If it did, you wouldn't have CBP checkpoints 20 miles from the US-Mexico border and you wouldn't have CBP officials inspecting vehicles and asking for documentation when leaving the US.
But only stupid terrorists would use global communication networks to communicate with each other. So the original premise stands. It's not like one Bin Laden's number two guys picked up the phone and had a detailed discussion with him about their next attack.
