From TSA's main webpage (http://www.tsa.gov)
as of midnight ET, 13 Aug 2008:

Does anyone know what a "checkpoint dosure" is? Not even my OED lists that word.

At any rate, does anyone find it disturbing (if not unexpected) that there's more lapses of security (breaches) than there are actual real issues?

Also, what is "artfully concealed"? Throwing my Gerber/Leatherman underneath my laptop in my bag?

And what constitutes a firearm in the TSA's definitions? Does this include the people who legally and properly check their weapons as baggage? I find it very difficult to believe 22 people would accidentally carry a weapon through a screening lane.
