We've always had mass murderers in our midst — but not in epidemic numbers as now. In 1948, a man named Howard Unruh shot up his neighborhood in New Jersey, killling 13 people. It didn't take long to declare him legally insane with a diagnosis of paranoid schizophrenia and lock him away for 60 years, until he died at age 88. True, like today, warning signs were given by Unruh and ignored like today. Still, 1948 was different. Very few murderous people slipped through the cracks. I remember talking to one psychiatrist at a state hospital in the early 1950s. He referenced one young man whom he saw as particularly dangerous: "As long as I am here he will never get out. He is a little murderer."
