Do any of the posters who believe violent crime is a result of "bad" parenting and video games realize that crime has actually been in decline since the early 90s? Here's a source, or you can just google it yourself: Crime Stats .

If your arguments were plausible, then crime should hypothetically be the highest it has ever been (after all we have way more access to violent games, etc than ever before) but it's not. The fact is that the only way to stop shooting rampages is to make guns illegal.
