Calling Bob Costas a "pretentious little man" is an insult to pretentious little men!
Costas appeared on Bill O'Reilly's show this evening (05-Nov-12).  O'Reilly asked Costas to picture himself in that Colorado theater last summer.  Wouldn't Costas have wanted to have a gun to defend himself against the body armored gunman?  Costas said it would probably have made the situation worse.  O'Reilly, a defender of the Second Amendment but no great proponent of gun ownership himself, said he would sure want a gun in that case.
So Costas would rather wait for a bullet while cowering on the sticky floor of a movie auditorium than take a long shot with a handgun at a nut-case who is hell-bent on killing as many innocent people as possible.  
Maybe my Psych major nephew is right.  He has been telling me for years that liberalism is a mental illness!
