The only 'improvements' we will see here in the US will be linked to $$ in someone's pockets and/or more invasion of privacy (passenger information).

There will be no review of procedures to see if improvements can be made there because no one will make a profit off a process change.

I find the references to carry-on bags disturbing. Both TSA and the airlines would be quite happy to find an excuse to prohibit carry-ons - TSA so their screeners have less work to do and the airlines because it will drive more checked bag revenue their way.
