I would actually argue it does improve security since you're spending more time on the people who have a higher probability of being a terrorist versus those that don't.

What doesn't improve security is just random screening where you're frisking 4-year olds and senior citizens and letting the adult males walk on by.

It takes months to years for the regulation and security to start direct profiling a specific group. It takes this group a few days to change strategy. It's not very effective to have tunnel vision.
