What the TSA could teach Congress about gun control

With the country continually in mourning over gun violence — we keep seeing mass shooting after mass shooting after mass shooting — it’s time to find ways to prevent it, lest we remain the “only nation where this regularly happens.” Those solutions needn’t be new, and could perhaps be kind of banal, like the risk-based decision-making behind TSA PreCheck screenings.

The Transportation Security Administration introduced TSA PreCheck in response to September 11 to prevent future terror attacks on airplanes. The system has a dual mission: expediting travel for people who submit to enhanced background checks and making everyone safer by allowing the government to focus on people who are considered risky or whose risk is unknown.

To qualify for TSA PreCheck, passengers undergo a screening process that determines whether or not they’re a risk. The process requires a questionnaire about biographical information and criminal history, fingerprints, and an in-person interview (exactly what’s involved in those background checks is classified). If approved, a so-called known traveler faces fewer security checks than everyone else. And by some measures, this system has been very effective. Experts say air travel has become safer even as threats have continued to evolve, partly since PreCheck allows the TSA to focus its attention on higher-risk travelers.
