Evading Airport Security
I fundamentally don't understand the danger of "traditional" (box cutters, etc.) weapons getting through airport security.  I understand that we need to continue testing for bombs and anything that can actually bring a plane down.<p>It would obviously be tragic and damaging for someone to attack "defenseless" passengers with "traditional" weapons, but -- in my eyes -- it's not terribly different from a random attack in the street or a shopping mall.<p>Airline personnel and the typical cohort of passengers would simply never let a terrorist take the cockpit, which effectively removes that entire element of danger.  The only super-substantial potential damage stems from an explosive of some sort, not a box-cutter, knife, or anything of the sort.<p>The cost of TSA (direct and indirect through delays, etc.) is immense, and truly does feel like security theater at this point.  I'd be all-for doubling down on bomb-sniffing dogs, behavior analysts, and all that; but this apparent focus on "traditional" weapons seems totally asymmetric to the risk it presents.
