Media reporters have pointed out that paragraphs in my Time column on gun control, which was also a topic of conversation on this blog, bear close similarities to paragraphs in Jill Lepore's essay in the April 23rd issue of The New Yorker. They are right. I made a terrible mistake. It is a serious lapse and one that is entirely my fault. I apologize unreservedly to her, to my editors at Time and CNN, and to my readers and viewers everywhere.
