At times, I have succumbed to the desire to be the first source to pass along a story, and I’ve gotten burned. Slate was one of the first outlets to tweet out that we had found the likely Facebook page of the man who was then being reported to be the Newtown shooter, Ryan Lanza. Shortly after that report, it was discovered—by, ironically, the New York Post among others—that the shooter wasn’t Ryan, but his brother Adam. In reporting that CNN’s Susan Candiotti had named Ryan as the shooting suspect, I was very cautious to cite a mainstream source. It turned out that the source was wrong, and this was one of the most embarrassing mistakes I’ve made as a journalist. —Slate Magazine.
