President Barack Obama announced plans yesterday to spend way too much money on a high-speed rail system. Apparently he's enthused because Amtrak has done so well.

But the one part that really got me was this one:

"Imagine boarding a train in the center of a city -- no racing to an airport and across a terminal, no delays, no sitting on the tarmac, no lost luggage, no taking off your shoes," said Mr. Obama in describing his vision for high speed rail travel.

You won't have to take off your shoes why exactly? A terrorist could still use a shoe bomb to blow up a train going at 200 mph. Of course, maybe the TSA will step in and make us take off our shoes before we get on Obama's trains.

But unlike airplanes, you don't have to actually get on the train in order to kill masses of passengers -- you only have to blow up the tracks.

How is Obama going to secure hundreds of miles of high-speed train tracks from terrorist attack? And how much extra is that going to cost?

Why don't we buy some more F-22s instead?
