There is zero proof that music, video games, movies, or any other form of entertainment causes people to become violent. Remember when David Hurcombe killed himself and his parents tried to sue Eminem because he listened to his music, and his parents believed the music caused him to kill himself? Yeah, they didn't win. Remember when the parents of Eric Harris and Dylan Klebold shot everyone at Columbine high school and their parents blamed Marilyn Manson because they listened to his music? Yeah, they didn't win that case either. There is no form of entertainment that causes people to become violent. Music, video games, and movies do not cause violent behavior, it is a mental instability that already exists in the person who executes violent behavior.
