As if TSA's relationship with the public weren't bad enough, it got strained even further a couple of weeks ago when news reports of its search of an adult cancer patient's diaper boomeranged all over the internet. If TSA really wants to improve its image, it wouldn't be hard to do. Here are just a few things that would transmogrify public attitudes about the agency.

1. Stop the Shouting. No human being responds well to someone shouting "Remove all laptops! Take out all liquids, aerosols, and gels! Remove all items from your pockets, that means ALL items!" at them at 6 AM--or any other time of day. Imagine walking into a Toyota dealership to find a uniformed officer there yelling, "If you want a Camry get in the left line; if you have credit question go to the right!" The best way for TSA to improve customer service would be to start treating people like customers instead of animals. They should establish a "no yelling or you're fired" rule. This alone would transform the atmosphere around the screening areas. And people might actually pay attention.
