Violence on television has been an issue for years, enough that the V-chip, which would allow parents to filter out shows with certain codes for violence, was supposed to be mandatory in all new televisions beginning January of this year. Computer software is available to block certain Internet sites. Right now, kids know more about computers and the Internet than the average parent who wasn't introduced to the technology until well past their formative years. You can't hide everything, nor can you can curb human curiosity. It's even harder now that, in light of efforts to prevent kids from finding bad stuff, companies are attempting to make the bad stuff find kids.
Parents are the most well-meaning, but the least equipped.
At least Hollywood has sophisticated screening methods to determine the amount, type, and intensity of films' content. If you ask an average parent who hasn't seen Kiss The Girls what it was about, they might think it was another Meg Ryan romance as opposed to a movie about sexual deviance and murder. Much as they might like to, parents simply don't have the time or money to pre-screen everything their child watches. That's Hollywood's job. Sometimes, the most well-meaning parents actually do more harm than good.
