Yesterday, NPR reported that 40 people in Los Angelees have died from”celebratory gunfire” since 1985. Where, exactly, do peoplethink bullets go when they are shot into the air? Into space? Ifit was that easy to achieve escape velocity, garbagemen would be out ofbusiness as we’d all just load our household trash into giants bullets forgiant neighborhood guns to shoot into space. In reality, bulletsfollow the generally true maxim that “what goes up must come crashingback down to Earth in a truly spectacular fashion.” Note toself: if you find yourself in LA for New Year’s Eve, remember to bringa Kevlar helmet.
