I do not think there is a strong connection between violence in video games and violence in real life. Honestly, people have murdered since before there were violent video games. People have murdered since the beginning of human existence and there were no video games back then to teach them violence. This analogy between video game violence and real life violence is utterly absurd because people were violent without video games. We do hear about shootings on what seems to be a frequent basis, but this is in part because we have a more efficient way of spreading information than in the past.
