This tragedy is all the fault of President George W Bush and the National Rifle Association.   President Bush dragged our nation into two endless wars in Afghanistan and Iraq.  The war in Iraq was never necessary at all, and our response to 911 should not have been to conquer and take over Afghanistan.  It has been 15 years since 911, and it is ridiculous that we still have troops in that nation.  If this Army Reservist had never been sent to Afghanistan, he probably would not have become so screwed up by the stress of being in a violent and dangerous war zone.  How many thousands upon thousands of American servicemen have come home screwed up mentally because of Bush's arrogant incompetence?

The other clear culprit to blame here is the National Rifle Association, for its vigorous promotion of the AR-15 rifle in America.   The NRA literally wants every American to own an AR-15 Assault Rifle!!  This is insane.
