Don't ask how I found this, but apparently I had a letter published by The Economist three years ago and didn't even notice. Idiot. It's about gun control, just after the Virginia Massacre, and actually all the responses are pretty interesting. As you probably guessed, the majority of the US respondents were anti- gun control and the rest of the world (ish) was pro. Nothing new there, then.
