The next terrorist attack at an airport on American soil will happen this way. A suicide bomber with a three large bombs will buy a ticket, not check baggage and find himself in the middle of a screening line with hundreds of travelers. He will have a large backpack and two carryon style suitcases full of enough explosives to destroy the terminal and everyone in it.
As I have said on this blog so may times. We must stop letting people fly on our planes carrying passports of countries that are at odds with the USA. We need to bring back the Fourth Amendment and stop searching Americans, What we really need are trained, armed professional cops profiling passengers from the point they enter any airport for behavior issues.
These poorly trained TSA workers are part of the problem rather than the solution
