Lockdown at Fort lee after soldier shoots herself

Although this is a rather small article I think it is very important because it branches off to something more.  Recently a women soldier at Fort Lee army base shot herself in the head.  This prompted a lockdown of the base but it was soon lifted and isolated.  I think this situation shows how bad soldiers coming home from active duty are actually doing and the true brutality of war.  This women's mental state must have been fragile and most likely unstable.  If she shot herself when she was simply mad, there must be something wrong.  What are your opinions; do you think that soldiers coming home from war are getting continuously worse with post dramatic stress disorder and what can we do to stop that or help further treat it?  How is war really affecting people, and how much is the government possibly covering up?    http://news.yahoo.com/active-shooter-reported-fort-lee-virginia-134136796.html
