Recognizing that media is not the sole cause of social changes, what cultural changes can you attribute, in part, to mediated violence?

I was asked this question on the Japanese TV show. With violence constantly being displayed on television, people may think that "lesser" types of violence are "ok" to committ. People are desensitized to the violence they are seeing, so they may be more inclined to commit acts of violence. I think that violence may also be comitted because of the confidence in the economy. People are losing faith in our economic system, so this may result in people doing acts of violence, like armed robberies, bank robberies, purse snatching, or other acts of cruelty.
