That Was Insane Yesterday

And there were hardly any details available because it happened on Christmas Day when newsrooms were vacant. 

The twist today is that the shooter was, they say, dressed up as Santa. I'm wondering how much of that is shock value. 

Edit: Best I can tell, Channel 8 was the first to name names. Fox 4 obviously knew who the gunman was in time for the 5:00 pm broadcast (they showed his house), but didn't name him for some reason.
