Having been through airport security screening five times in the last six days, I am officially in favor of abolishing all security procedures and allowing all passengers to go directly to their planes.
Then, after that, we can see whether or not there are any bad consequences to such a policy. It is perfectly possible that there would be none.
If there are, we could give real consideration to the costs imposed on every single passenger by such procedures and determine whether or not it is worth imposing these costs in order to prevent a somewhat greater harm to a few.
