[UPDATE]: Thankfully, early reports that Congresswoman Giffords had been killed were premature; tragically, four people have been reported dead.  After shooting Giffords, the shooter reportedly fired into the crowd indiscriminately until he was subdued by heroes on the scene, including at least one member of Giffords’ staff.

Details still sketchy, but she was apparently shot in the head at point-blank range; NPR reports that at least five other people were shot before the gunman was subdued.

Pray for her and the other victims.  This was abominable.
