A person who knows law could still offend against the law on purpose. Actually, most intelligent criminals are usually familiar with law. A person who doesn't have enough knowledge of law but has morality in mind, by contrast, rarely has illegal behaviors. Since we all know that law is the lowest standard to regulate human’s behavior, we should pay more attention on morality regeneration initiative instead of law reinforcement only to prevent crime. I would like to talk about how morality regeneration initiative in the areas of home education and social network could enhance crime prevention.
