The European response so far
No, no, no.
You guys have missed the point (except Huck).
The box cutters are merely symbolic of the failings of airport security.
Whoever planted these knives may have just as well planted shoes with fuses hanging out of them.
Certainly a shoe with only a fuse is harmless but if you tried to pass security with one you'd find yourself tackled and hog-tied.
Someone is trying to make a point and I think it's a pretty good one.
The truth is anything can be a weapon. And airport security is a sham.
Whoever is planting boxcutters is saying essentially the same thing.
