I'm putting together some research for a possible book, titled, for now, "Boxcutters, Icepicks, and a Gram of Polonium: the story behind history's most infamous murder weapons." I honestly can't tell you fully why. I just find it fascinating that, for starters, in the case of the boxcutter, such a simple weapon could be used to pull off what remains one of the biggest crime in history. And the story of that Russian killed by polonium poisoning - fascinating, horrifying, compelling. Is there something to learn from such things? I don't know. Maybe it's just unhealthy fascination with the macabre.
