So, as I mentioned last month, somebody is making a point of assembling weapons made entirely of objects found inside airport security checkpoints.

Nothing will come of this, of course. Bruce Schneier explains why:

So, what’s the moral here? It’s not like the terrorists don’t know about these tricks. They’re no surprise to the TSA, either. If airport security is so porous, why aren’t there more terrorist attacks? Why aren’t the terrorists using these, and other, techniques to attack planes every month?

I think the answer is simple: airplane terrorism isn’t a big risk. There are very few actual terrorists, and plots are much more difficult to execute than the tactics of the attack itself. It’s the same reason why I don’t care very much about the various TSA mistakes that are regularly reported.

He’s completely right. As usual. 90% of the money and effort spent on the TSA checkpoints today is wasted, and we’d be better off if we used those resources for other things.
