Schneier continues the debate:
In 2004, the average extra waiting time due to TSA procedures was 19.5 minutes per person. That’s a total economic loss—in –America—of $10 billion per year, more than the TSA’s entire budget. The increased automobile deaths due to people deciding to drive instead of fly is 500 per year. Both of these numbers are for America only, and by themselves demonstrate that post-9/11 airport security has done more harm than good.
