In 1791, the right to bear arms to defend against an over-reaching government wasn't theoretical. Today, it's hard to imagine physical weapons serving the same purpose. But it's easy to see how hacktivists might - especially if you broaden the opponents to include hate groups and rapacious multinationals.

From 1961 to 1964, I was fortunate enough to work at a think tank in the Kenwood neighborhood of Chicago. As a writer and editor, I reported in a publication about the thinkers. Our offices were in a former mansion; I worked in what had been the ballroom. As I sat typing my copy, I imagined the dancers waltzing.
