Should We Ban Violent Video Games? 

  So, if violent video games trained up a mass murderer in Newtown, Connecticut, shall we outlaw them, in the name of protecting society?
   Venzuala has outlawed them. Brazil has outlawed many of them, making it illegal to possess, own, import, or sell them.
   Should America follow suit?
   In June 2011, a California ban on selling violent video games to children was yet to take effect when the Supreme Court stepped in and ruled, in the name of free speech, that the ban was illegal.
