Does the media reduce crime?

If you kill people in video games, are you less likely to do it in real life? If you watch someone smoke on screen, are you less likely to do it in real life? I’ve noticed that when I can do or watch something virtually, I’m less likely to do it in real life because of the added risks. Virtually smoking isn’t harmful like real smoking, right? Does anyone else feel the same way? I really don’t like how there is a War on Media, when there are more serious things to deal with, like how many people are unemployed and many people are having children to get on welfare. There are many times when a character, like Duke Nukem, smokes because it adds to his masculine character. Would I ever smoke? No, but I would rather do or watch it virtually.
