I think we need to make the Anarchist's Cookbook widely available for assorted nut jobs everywhere. The recipes are the most unstable way possible to build a bomb. As long as neighbors aren't harmed in the process, it's an easy way to eliminate extremists of all breeds.
Yeah, it's too bad most of the ones who really wish us harm though are not "amatuers", but rather intelligent and mostly well-educated (or in the process of becoming so...).
