This occurred to me, too. This is the coverup of a major screw up perhaps, that ended with the death rather than the capture of OBL.
That actually provides another way of understanding the golf shirt. Obama knew the operation was going down, but as a secret snatch, which he could then reveal at whatever time suited his political purposes, I should think late next year, perhaps. So he stayed away from the operation, for plausible deniability purposes. But then it all starts going wrong. The chopper crashes, the event becomes unhidable, and with OBL's unexpected death, the threat of immediate repercussions, including Al Qaeda reprisals, goes immediately to the front burner, and must be publicly discussed. So He is called in suddenly off the golf course because now it must seem that he was in charge and say, like Peewee Herman, "I meant to do that." This, BTW, takes OBL off the table too early to be meaningful during the 2012 elections. Conservatives just caught a break.
