Blame the criminal perp who had a government security clearance and bought the gun or guns legally with background check. He broke the gun-free zone law and teh law against murder. So why is the first response of the President and others to say we need more laws that would target others who didn’t break any laws?
If any laws are to be change, REPEAL the gun-free zone laws where virtually all mass murder shootings occur. But IF those are good and effective laws, apply them EQUALLY everywhere–including the White House and Congress.
