This story makes me very sad. I don't see anything good coming from folks carrying concealed weapons to protect themselves against random shooters. I don't even pretend to have to answers to this craziness, but having fearful adolescents carrying firearms seems like a horribly bad idea. How do we, as a society, grab the reins of reason?? How CAN we protect ourselves against unexplained and seemingly unmotivated violence?? Some questions just keep me awake at night. I suspect I'm not alone.
