How many laws are really necessary? It's like hate crimes. Is not every crime a hate crime of some sort? Do we really need a specific hate crime? No. But what is happening is the public crying out for the government to do something about the crime in the nation. Since the government cannot take any proactive action the only thing left is to make more laws.
Where the problem lies is not the lack of laws but the lack of teeth in the laws. Real punishments need to happen when laws are broken. Chain gangs, whipping and execution need to happen simply to tell every potential lawbreaker that there will be real punishments when laws are broken. As it is now, there are people that commit crimes just to be sent to jail because of the lax atmosphere in the penal system.
