Shame is a great teacher, and brevity turns out to be the soul of contrition, too.
But even at four minutes, the president's speech was about three minutes too long. For it was not only an apology, but an apologia. What a pity he didn't stop with the apology but had to append the usual attack and campaign ad. Bubba before his 'speech'. If he'd taken that ROTC course he once signed up for, maybe he would have learned to apologize and stop.
