Bruce Schneier says that the TSA's thoughts about security at smaller airports are exactly the conversation they should be having:
Last week, CNN reported that the Transportation Security Administration is considering eliminating security at U.S. airports that fly only smaller planes -- 60 seats or fewer. Passengers connecting to larger planes would clear security at their destinations.
To be clear, the TSA has put forth no concrete proposal. The internal agency working group's report obtained by CNN contains no recommendations. It's nothing more than 20 people examining the potential security risks of the policy change. It's not even new: The TSA considered this back in 2011, and the agency reviews its security policies every year.
We don't know enough to conclude whether this is a good idea, but it shouldn't be dismissed out of hand. We need to evaluate airport security based on concrete costs and benefits, and not continue to implement security theater based on fear. And we should applaud the agency's willingness to explore changes in the screening process.
There is already a tiered system for airport security, varying for both airports and passengers. Many people are enrolled in TSA PreCheck, allowing them to go through checkpoints faster and with less screening. Smaller airports don't have modern screening equipment like full-body scanners or CT baggage screeners, making it impossible for them to detect some plastic explosives. Any would-be terrorist is already able to pick and choose his flight conditions to suit his plot.
And just think, it's only taken 15 years and $45 billion to get here...
