1. No more banned items: Aside from obvious weapons capable of fast, multiple killings—such as guns, toxins and explosive devices—it is time to end the TSA’s use of well-trained security officers as kindergarten teachers to millions of passengers a day. The list of banned items has created an “Easter-egg hunt” mentality at the TSA. Worse, banning certain items gives terrorists a complete list of what not to use in their next attack. Lighters are banned? The next attack will use an electric trigger.
2. Allow all liquids: Simple checkpoint signage, a small software update and some traffic management are all that stand between you and bringing all your liquids on every U.S. flight. Really.
3. Give TSA officers more flexibility and rewards for initiative, and hold them accountable: No security agency on earth has the experience and pattern-recognition skills of TSA officers. We need to leverage that ability. TSA officers should have more discretion to interact with passengers and to work in looser teams throughout airports. And TSA’s leaders must be prepared to support initiative even when officers make mistakes. Currently, independence on the ground is more likely to lead to discipline than reward.
