The most terrifying event of the post-election meltdown in American civility is not the riot at the United States Capitol on January 6, 2021, but the Christmas morning bombing in Nashville, Tennessee.

I know what I write about. In the 1980s, I was an editor at Loompanics Unlimited, publishers of controversial and unusual books, sellers of such titles as The Anarchist Cookbook, Kitchen Improvised Plastic Explosives, and Homemade Guns and Homemade Ammo. We published books on making bombs, modifying guns, and causing mayhem. The First Amendment to the U.S. Constitution says words cannot be prohibited, only actions.
