Media doesn't make people murderers. I've played violent video games, listened to heavy metal and rock music, watched horror movies, WWII documentaries with actual filmed killings and I've never beaten my kids or wife.
Osamabama talked a good talk about Hollywood being to blame but he never had any intentions of going after anybody but the NRA and gun ownership. It's true that movies are more violent than they were in the 50's but so is the world. The real blame lies in the fact that parents don't teach their kids values anymore and the government run schools don't allow right and wrong to be taught thanks to the "progressive" liberals who have been destroying our schools since the 1970s.
