One of the great scandals of the last eight years is how successful the Bush Administration has been at avoiding appropriate accountability and oversight. Whatever else one thinks of Don Rumsfeld, he at least (appropriately) offered to resign -- twice -- after the Abu Ghraib prison scandal broke. The president, of course, declined to accept, but such displays of honor and acceptance of responsibility have been rare during this presidency.

Andrew Sullivan notices this bit of self-justification from JohnYoo:

Would we have wanted President Abraham Lincoln to worry about his personal liability for issuing the Emancipation Proclamation freeing the slaves (done on his sole authority as commander-in-chief)?
