We still don’t know what was behind the killings at Fort Hood this afternoon, in which 11 soldiers and the killer died, but President Obama’s rushed press conference was surprising in its flippancy nonetheless. Before he got to the issue on everyone’s mind — namely the deaths of Americans in uniform — the president gave a “shout-out” to government bureaucrats gathered for a previously scheduled conference at the Interior Department, complete with appreciative chuckles. He treated the event like a pep rally rather than a tragic occasion with a wider audience than those gathered in the room. I wonder how many media outlets will compare Obama’s performance to President Bush’s “Pet Goat” moment on 9/11. I won’t hold my breath.
