It's in the misery of some unnamed slum that the next killer virus will emerge. - Barack Obama

Now, I don't know, not having been there and not seeing all the facts, what role race played in that. But I think it's fair to say, number one, any of us would be pretty angry; number two, that the Cambridge police acted stupidly in arresting somebody when there was already proof that they were in their own home; and, number three, what I think we know separate and apart from this incident is that there's a long history in this country of African-Americans and Latinos being stopped by law enforcement disproportionately. That's just a fact.

The absence of even rough agreement on the facts puts every opinion on equal footing and therefore eliminates the basis for thoughtful compromise. It rewards not those who are right, but those - like the White House press office - who can make their arguments most loudly, most frequently, most obstinately, and with the best backdrop.

To all those watching tonight from beyond our shores, from parliaments and palaces, to those who are huddled around radios in the forgotten corners of the world, our stories are singular, but our destiny is shared, and a new dawn of American leadership is at hand.
