Why aren’t we talking about guns? A week before Easter, three Pittsburgh police officers were shot and killed while responding to a domestic disturbance. Apparently they were met by a 22-year-old man wearing a bullet-proof vest and armed with several guns, including an AK-47 assault rifle. On the same weekend a man in Graham, Washington, shot and killed his five children before turning the gun on himself. The previous Friday in Binghamton, New York, a man shot 17 people in the office of a civic association, killing 13 of them, and then killed himself. Several days later in Priceville, Alabama, a man with a handgun shot and killed his wife and 16-year-old daughter, his sister and her 11-year-old-son and then killed himself. In Chicago a staggering number of public school students—more than 30—have been shot and killed so far this school year, either caught in gang crossfire or deliberately targeted by gangs.
