I question your theory that the Bible was used as a device to police and control people. The fact is that the Catholic church made the production and reading of the Bible a capital offense. It kept it as a "forbidden book" for generations only to be read and used by the clergy of the church. Finally, when courageous men like Wycliff and Tyndale along with others produced and distributed the Bible in the vernacular people saw just how unscriptural the Church was and threw off its yoke of slavery.
The Bible was actually a book of liberation and freedom. It was the institution of the church that policed and oppressed the people.
