First off, my HEART goes out to Victims FAMILIES and Loved Ones.  I am a GUN Guy, have been my whole life.   MY HUGE Problem with this is, ""He had been treated by mental health professionals throughout his childhood."  OK, RED FLAG Warning.   BIG Long Track Record.   Mr. Harper-Mercer should have been LOCKED Up in the State Mental Jail,  and removed from Society.    There would be NINE people still alive.   Secondly, these MENTALLY ILL people HAVE to be Monitored and their Mentally Ill status and information entered into the FBI computer data base which  informs GUN Dealers, GUN Sales whatever.  So when a person with a history of Mental Illness goes in to buy a GUN, their info comes up on the stores computer, and they are DENIED, NOT Allowed to purchase a GUN.....The Gun Laws and Mental Health  personal information laws HAVE to CHANGED.   The Mentally Ill are to protected and are KILLING Lotsa People...............
