That's right, we allow things like this to happen.  How?  These crazies target large groups of people who DO NOT HAVE GUNS.  In my state there is a church, years ago in response to church shootings in Florida they decided to have security who are packing.  One day a man had an argument with his wife and decided to go to this church and shoot it up; when he realized he was outgunned he backed off.  You can't get rid of guns, you can ban every single one and there will still be guns.  What happens to a nation without any guns?  They are defenseless in an advanced technological age.  Rather than being like the liberals and Obama prefer to make us a perpetual victim, we must empower ourselves.  I propose requiring employees of these public places to carry.  It may not eliminate all the deaths but it will severely minimize them.  This is another tragedy that could have been averted, I hope some learn from this and are prepared for the slight chance of this happening to them.
