Security idiocy

I rarely agree with Maureen Dowd, but she's dead-on with this:

I get flagged for extra security every time I buy a one-way ticket, which seems particularly lame. Doesn't the T.S.A. realize that a careful terrorist plotter like Mohammed Atta could figure this out and use his Saudi charity money to pop for round trips even if the return portion gets wasted?

I can't tell if the TSA is under- or overestimating the intelligence of the terrorists, but one thing's for sure -- this is bureaucratic idiocy.
