It doesn't surprise me that violent people are drawn to violent games, and that it can cause their behaviour to get worse. The danger in these programs is that some people will think that because a minority don't react well to games they should be banned to everyone.
The trick is more to watch out for the signs that something is "up" with these kids, not blanket-restricting a valid form of entertainment. Pretty much anything can pose a risk to someone somewhere, but it doesn't make sense just to outright ban things.
I also don't think this "blame the parents" thing helps entirely either. Yes, disturbed kids tend to come from bad homes, but not always. I'm pretty sure there's exceptions.
