And they are as stupid as the people who say that guns kill or SUVs cause accidents.
It is the people who kill, not their tools.
Anything, almost, can be turned into a weapon. A shoelace, for example, can be used to strangle someone. Pencils, plastic forks from the dinner tray, many things can easily be turned into weapons.
The ultimate idiocy is the full-body screening of the pilot. The pilot doesn't need a bomb or box cutter to bring down a plane. All he has to do is drive it into the water, like the EgyptAir pilot who crashed his plane off Nantucket while intoning "I rely on God," killing all on board.;-))
But we must not bring that up. We pretend that we go through this nonsense as a small price paid to ensure the safety of air travel. Rubbish. This has nothing to do with safety - 95 percent of these inspections, searches, shoe removals and pat-downs are ridiculously unnecessary. The only reason we continue to do this is that people are too cowed to even question the absurd taboo against profiling - when the profile of the airline attacker is narrow, concrete, uniquely definable and universally known. So instead of seeking out terrorists, we seek out tubes of gel in stroller pouches.
