Your problem is that you said "decent designer". There are no "decent designers" within the government.
Look at all the kids that get tagged by the system because their name matches some 50-year old terrorist. I recall a family travelling from the UK to Disney World and they got pulled into additional screening three times because their young son's name matched a name on the watch list.
So each time, limited resources were spent on 'checking' a young child. Meanwhile, suspected terrorists walk right through security. It's a complete joke.
"The 5-year relative survival for thyroid cancer is 98%. This means that, on average, people diagnosed with thyroid cancer are 98% as likely to live 5 years after diagnosis as people in the general population."
...or drop the ball like they did with the Boston Marathon bombers.
It's okay to travel to a part of the world known for terrorist activities and return back to the USA and then have a foreign intelligence agency ask the FBI to look into a few guys. But it is not okay for you to travel if the name of your 2-year old son matches a name on the no-fly list and then the same thing happens when he is 8-years old.
Yup, DHS is doing a wonderful job fighting terrorism.
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?
