Recently the Michigan House of Representatives passed and sent to the governor a bill that, among other things, makes it easy for people to carry concealed weapons in schools. After the massacre at Sandy Hook Elementary School Friday, a spokesman for House Speaker Jase Bolger said that it might have meant “the difference between life and death for many innocent bystanders.” This is a popular theory of civic self-defense that discounts endless evidence that in a sudden crisis, civilians with guns either fail to respond or respond by firing at the wrong target.It was perhaps the second-most awful remark on one of the worst days in American history, coming up behind Mike Huckabee’s asking that since prayer is banned from public schools, "should we be so surprised that schools would become a place of carnage?"...We have to make ourselves better. Otherwise, the story from Connecticut is too unspeakable to bear....On Friday, the president said: “We’re going to have to come together and take meaningful action to prevent more tragedies like this, regardless of the politics.”Time passes. And here we are.
