And once again the TSA leads the world in the thinking that it's more important to take pointy objects away than to go after people with ill-intent.

Were HKG not (sort of) part of authoritarian China I might have made the point that I could fly business or first class, smash a glass against the wall and thereby create an object on the plane far more deadly than a few small screwdrivers.

But I tend to demure on those issues overseas as I don't know precisely what my rights would be in case of arrest. I choose to fight these battles in my own country, so I'm not faulting you there.
