I just finished Bill Mauldin's book 'A Sort of Saga'. Seems like this kind of stupid used to be pretty common, Darwin seems to be asleep at the switch a lot.
This is why I have the 5 year old girl in my head all this time. Boyfriend came home from work after arguing with boss and "meye rye-eets" his started zipping SKS rounds though the wall. One caught her right below the hair line. I won't unsee that.
