The problem is that the TSA is not interested in science or efficiency. They are about maintaining their bloated kingdom. If they were about science and efficincy they would never have rolled out the BDO program. They would have a mechanical system in place to move empty bins from airside to landside without the need for a highly paid human to move them. They would know that gate ID checks and VIPR teams at train stations will do nothing to make anyone safer.
Any business that was forced to cut 8% of their budget would not do ANYTHING that would impact the customer in any significant way. Travel gets cut, housekeeping reduced, new purchases deferred, etc. Hours reductions and layoffs come in if the less painful cuts can't meet the requirement. Those left get stuck working harder to meet customer needs.
In the government case, they jump straight to "you will have to wait longer Mr. Forced Customer" and don't seem to care about any of the massive wastes already in the system.
