[Margaret Pilkington]

That wasn't the question.

If children don't read then the violent books are not an issue.....and there is evidence in Educational studies that children read less now than they did 20 or 30years ago....although the Harry Potter books did some good in reversing this trend.
Children mimic what they see, they copy.......and if they watch inappropriate things on TV, then they may be influenced by what they have seen...especially if they do not have adequate role models in the home.
I don't really blame TV, or the internet.......parents are the arbiters of good reading, good watching, and the sensible use of other media forms.
