I agree with the consensus that a police officer in every classroom is not practical and asking the pacifist hippie socialist teachers to defned anything other than abortion rights is even less so. Why not have each child bring their dog to school? Bad guy shows up intent on murderous carnage and 20 canines dedicated to protecting their masters chew the evil galoot up. Cost of the program, maybe 50 pounds of Purina Dog Chow per day. I can already hear the argument, but keep in mind, when I went to elementary school, a lad's dog went with him and sat outside until school was over and walked us home. A lot of dogs were without, children weresafe within.
