Mature Videogames are for Mature People Only

Don't you find it annoying when you see a kid just walk in a video-game store and walk out with the latest version of Grand Theft Auto? I think video-game stores should enforce the rating system much stricter and less lenient. If these kids can simply walk into the store and buy these extremely violent video-games then what's the point of the rating system? All these kids can get harmed by these games and can get influenced badly. These games might make them more violent and aggresive and can alter their perception of reality. The employees of the stores should check their ID to make sure they are at the right age to experience these games.
