I had written an op-ed for The Wall Street Journal decrying the fact that so many parents in the United States were not allowing their children to receive measles vaccinations, which in turn had led to a spike in cases of this hypercontagious disease.31 The envelope was a cornucopia of vaccine conspiracies with a typed note specifically addressed to me. Instinctively, I looked around but saw no one who wasn’t supposed to be there. Someone had to have known where I sat and worked and dropped it there. It was one of the creepiest things to ever happen to me.
