I personally believe that this is just a way for parents to excuse their children's bad behaviour by blaming television instead of their own bad parenting. Now, in some cases this might be true but you should never generalise and I feel that this is what many parents in situations like this do. Instead of taking responsibility and teaching their children right from wrong. I'm not saying that children cannot learn violent acts and bad behaviour from watching television but if a parent is active in their children's life and actually cares about what their doing normally the television won't cause the kids to be violent because they are being taught how to act and what's right and what's wrong. I'll say again, this might not be true in some cases but I'm of the opinion that television in it self does not cause violence in kids.
