Speaking of pointless security measures (again), Eric made an interesting observation yesterday. Now that airplane cockpit doors are locked, what is the purpose of forbidding sharp items on flights? Sure, someone could take the entire airplane hostage and start threatening to cut people. But that would gain them nothing, as no pilot would give in to their demands.

This looks like a good example of how security measures stay in place even after they’ve outlived their usefulness. Things get onto the forbidden list far more easily than they get off the list.
