As an educated man, I can understand the pathology behind the actions by these 'men'. As a teacher I am horrified. As a father, well...I'm a gentle giant, but kill a child and all bets are off.
I, too, believe this is a desperate cry by these evil men to 'notice' them, to pay attention to their demands, instead of the demands of other evil men with more power and effect on their surroundings. How any sane person could think you would get either sympathy or support from killing children...no. This is the definition of terrorism--to instill fear and terror, and to force those so terrorized into doing your will. It is bullying writ with a gun. These people have shuffled off their humanity. They aren't doing this for a cause, but for the simple need to wave their murderous, bloody hands in the air and demand attention in an attempt to bolster their own miniscule ego.
