Most mass shootings in the USA are committed in Gun Free Zones. The laws are counter-productive and serve no purpose other than to get people killed. You cannot prevent violence by disarming the victims and Chicago and DC prove my point.
It is time to take action. Ban all gun-free zones, honor the lack of enumeration of gun control, stop trying to use the Interstate Commerce Clause as a catch-all for every illegal law you want to pass, and honor the oath you took when you were elected.
Gun Free Zones are Death Zones. Let people defend themselves!
