How and I mean how politically? No politician wants to be the one blamed for reducing our "security". No airline wants to pay for this.
Well let’s go back to pre September 11th airport security.
At the time box cutters were permitted since they were less than 3” (I think was the length) knife. The ONLY other thing that has happened with airport security was Richard Reed the Shoe Bomber. BTW, it was the people in the plane that stopped Richard Reed .
The TSA is NOT needed. They have done more harm than any good. Air travel is down since the TSA has been created. They have not only cost the airlines and all the people associated around it. They have hurt tourist and vacation places too.
If the government was really concern about terrorist, then they would secure the borders. The only people they seem to want to target are babies, grandma and veterans.
