Schools and Internet Censorship

Sometimes I believe that schools go to far censoring their students from material on the web. If the kid can't get at it in school they are just going to go home and find it. The schools are most likely looking out for their own interests so that they don't get sued. YET! Their are kids who are having sex and doing drugs in school while its in session (disturbing but true) yet the school cares more about censoring what's on the internet. I think there should be an even balance of punishment in school. People stop paying attention to what's happening right in front of them and become more concerned about what's going on online. That's just my opinion and I hope it doesn't offend anyone.
