Las Vegas, Money, and a not so warm, fuzzy feeling

Some odd points about yesterday.
While America was reeling over the horror that happened in Las Vegas, I was surprised to see that not everyone was horrified.  You say "WHAT?  How could anyone be anything but shocked?"  Well, investors weren't.  The Dow Jones went up 152 points.  For those who don't know, that's a lot of stocks.  At a time when many were shocked senseless by the sheer magnitude of death and suffering caused by one, lone individual, there were those out there more concerned with making money.  So, am I the only one who sees a correlation there?  Between money and evil?  That times of horrible evil are also times to make lots of money?  To turn death and horror into profit?  I hope not.  Yet there are those out there who thought it would be very good for their bank accounts.  Now, isn't that frightening?
And could someone please explain to me what a "warm condolence" is?  I have no idea.  Isn't a "warm condolence" a paradox?  Warm and fuzzy, and yet sorry and sad.  The definition of condolences is :  an expression of sympathy, especially on the occasion of a death.    So can someone please tell me about warm sympathy?  I ask this because the Idiot Jerk in the White House sent "warm condolences" to the victims families and the survivors of the Las Vegas Horror.  I suspect that this is about as heartfelt as he can get since he, himself is the epitome of shallow insincerity. 
Finally, I would remiss if I didn't point out that Nevada, with it's most liberal gun laws, has suddenly become the poster child for gun control.  The fact that one very crazy man can amass a collection of 23 guns in a hotel room without anyone raising a flag is... well, it's as horrifying as the horror he unleashed.  This man may have actually walked through the lobby, a high powered rifle in each hand, and no one would have said a thing because he wasn't breaking the law.  He may actually have carried his armory bit by bit, across the lobby twelve or more times.   Think about it.
