Obama can’t let it go because he is the president (as he has reminded of this right out loud at least three times) and cannot let some mere policeman get in the last word or get the better of him
Obama is compulsive on this. I’m sure his advisers told him to let it go
I get the feeling that Obama has hired the same "advisers" that Michael Jackson" hired.
