This young Saudi, living in the windy, isolated West Texas city of Lubbock on a student visa and, therefore, apparently attending Texas Tech University (though they managed to keep their name out of the stories), got caught buying some unusually-toxic industrial chemicals.

We’re lucky that Khalid Ali-M Aldawsari isn’t the finest product of human evolution. Or, uh, maybe he is. This could well be evolution at work.

Why is that some people start building bombs immediately after learning some basic chemistry? Do they play out some repressed childhood miseries?
I have built enough explosive things as a kid, I remember.
I set a lot of fires, mainly in plastic models I was tired of looking at. But I never had a religious motive for it.
