Is it sad that I am not surprised that an angry man walked into a school and shot all the girls and only the girls? From the New York Times:

A dairy truck driver, apparently nursing a 20-year-old grudge, walked into a one-room Amish schoolhouse here Monday morning and systematically tried to execute the girls there, killing four and wounding seven before killing himself, the police said… “He wanted to find female victims,” said Col. Jeffrey B. Miller, commissioner of the Pennsylvania State Police. “This was a target of opportunity.”
