The President has released a statement appealing for calm, etc.
The funniest line was, "But we are a nation of laws, and a jury has spoken."
You've got to give Obama credit for being gifted at these tiny lawyerly passive-aggressive verbal digs: "a jury has spoken," not "the jury has spoken."
This choice of indefinite over definite article doesn't commit the Obama Administration to any action, but holds out hope for Obama's supporters that Obama will have his feds subject Zimmerman to double jeopardy in front of another jury. (The Justice Department just announced they are mulling trying Zimmerman over again.) Plus, it quietly questions the legitimacy of a jury with no blacks on it, suggests that a different jury would have found differently, and so forth.
Of course, 99% won't notice the difference, but Obama probably feels pretty satisfied about his wording right now.
Well played, Mr. President!
