There are ways to possibly reduce gun violence that don't involve the passing of more laws.  Here's one.  The United Nations' World Health Organization says ever year billions of dollars are spent worldwide on injuries related to punching incidents.  If you could reduce punching incidents, it should follow that gun violence should decrease too because punching incidents often evolve in to using more deadly weapons - guns, knives. etc.  So with fewer punching incidents, there should be fewer gun incidents.  One Punch Homicide - a documentary - could reduce punching incidents.  It's getting great reviews, and can be seen free at www.onepunchhomicide.com, where its reviews can also be read.  ShelterMe Nebraska, a domestic violence shelter, wrote "I encourage you to show it to your kids." on its facebook page about it.  It looks at 37 cases where someone was killed with one punch and only one punch, and half the film interviews five inmates who killed someone with a single punch.
