Would Amy and Chuck Schumer’s plan for tighter gun control decrease mass shootings?

Amy Schumer has teamed up with her cousin, Senator Chuck Schumer, to call for tighter gun control. The actor has been vocal about her support of greater gun control in the wake of the shooting of two women at the screening of her own movie, Trainwreck. The shooter, John Houser, had a history of mental illness yet legally obtained his gun. The Schumers are calling for a three-part plan that will make it more difficult for violent criminals and mentally ill people to acquire firearms. The proposed legislation has a reward and punishment system. States that submit all required records into the background check system receive a monetary reward and states that fail to comply are punished. Sen. Schumer also asks Congress to continue funding for mental health and drug abuse programs. They believe that this plan will decrease mass shootings. Do you agree?
