This is a reasonable argument, but we should pay attention to both the good and bad effects when tallying the value produced by the TSA. After adding up all of the terrorist attacks prevented by enhanced screening (zero?), we should be sure to subtract the wasted hours of people waiting at airports and the deaths caused by increased use of cars for moderate to long distance travel.[0] In the unlikely event that our analysis finds that the TSA saves lives, we should then compare it to other methods of saving lives and be sure to implement only the most cost-effective ones, potentially shutting down programs that are not as cost-effective.
