automatic weapons ,hate,terror

What do these three issues have in common.Killing.An automatic weapon should only be in the hands of law enforcement or a solider in combat.One does not need an automatic weapon for self defense!If they think they do then a mental health evaluation is needed Infact if any one wants to own a weapon then a mental health evaluation should be required and renewed every four years!Why is that so difficult!Also the examination shall be paided by the person who applies to own a weapon         Also the hate must stop.When the hate stops the terror stops!.
