Its up to the parents to monitor and punish these behaviors. The ratings system is more like a guideline not law so therefore it cant be enforced. Even if it was to become law it would be impossible to enforce as our law enforcement officers dont have time to do this. Parents need to be informed and monitor their kids on these games and not use them as a babysitter. Also there is no scientific evidence that playing violent games leads to vandalism or other violent behavior do your research before you decide to spread your false claims as facts.
