Maybe the best quote about this moment:

"When justice is done, it brings joy to the righteous but terror to evildoers." -- Proverbs 21:15

I don't know if the children of the New York City firefighters, and the thousands of others, who died on 9/11 are feeling joy right now. But I hope they feel some measure of satisfaction. And I hope that they continue to be consoled by a nation whose leaders did not forget their suffering.
I'm going to try to get a little sleep, though my mind is racing. I'll be back soon.
