You can follow all the news at just about any media site or blog. All I want to add is this:

1. Pray for those injured in the attack and the families of those killed.
2. This was an evil act.
3. Blaming any political party, movement, ideology or individual (other than the shooter himself) for this attack is stupid and dishonest. [Warning: Link goes to birther moron.]

UPDATE

Case in point: Shorter James Fallows: The guy's probably a nut and it's no one's fault -- except Sarah Palin's.
