Just to summarize the facts in this convoluted affair: Hagel did attend the Greene funeral. Obama and Biden did not. Nixon did not attend the Dillard funeral, and Bush did not attend the Maude funeral. There is no “tradition” of presidential attendance at generals’ funerals that Obama “bucked.” The Hagel misinformation (passed on erroneously by me) came from Drachenberg’s tweet, amplified in the Legal Insurrection post. The Nixon and Bush misinformation was a deliberate falsehood spread by Davis.
There are several lessons to be drawn from the affair. The first, and most important, is to be skeptical about everything one sees on the Internet and make a good-faith effort to ensure that information one passes on is accurate. I will certainly redouble my efforts on that score in the future. The second lesson is that when one makes a mistake, correct it as quickly as possible, more than once if necessary. And the final lesson, narrower but still important, is: Never trust a word Morris Davis says; it might be “sarcasm.”
