The new threat? - Al queda chemical weapons

[Arthur Dent]

I really don't buy the "It takes years of planning" argument.

I mean, how long did it take a couple of teenagers to pick up a few guns and shoot up a school? I can see it taking a lot of planning if your trying not ot get caught, but these are suicidal attacks!

How much planning does it take to steal explosives from a construction site, then drive immediately to the nearest bridge and set them off? Or get a bunch of guns and walk into a building full of people.
