should the state be enforcing morality?

In Does God need a police force?, Hesham Hassaballa takes aim at the religious police employed by certain countries like Saudi Arabia and Afghanistan:

Where did this concept of a "religious police" come from, anyway? It is a concept totally foreign to Islam and its principles. Islam, as all other religions, has certain rules and regulations that adherents must follow. Yet, no where in Islam does it say that these rules and regulations must be forcibly enforced. Although Saudi Arabia and Iran (and Afghanistan before) claim to be Islamic theocracies, the only true Islamic state in history was that of Medina at the time of the Prophet Muhammd (peace be upon him). The Prophet never formed a "religious police" and unleashed it upon his followers. The Prophet Muhammad instilled in his companions a deep love for God and His religion. He taught them how to be truly Muslim through his personal example, and thus those who were around him willingly followed Islam's regulations.

Hear, hear!
