In part that's right. However, the proliferation of violence on TV has helped create a world where shooting someone is 'acceptable'.

"Preschoolers overwhelmingly prefer and pay close attention to cartoons(33) – a format that is particularly violent. Saturday-morning cartoons, for example, have 20 to 25 violent acts per hour compared with five violent acts per hour in prime time programming.(34) With their preference for cartoons, preschoolers are therefore being exposed to large numbers of violent acts in their viewing day. Based on their viewing patterns, it has been estimated that, by the time they start school, children will have seen an average of 8,000 murders and 100,000 assorted other acts of violence and destruction on television.(35)"
